If a woman is pregnant with more than one baby the HCG beta levels will be significantly higher and should also double as with a singleton pregnancy. If the levels do not double there might be a possibility of a non-viable intrauterine pregnancy or an ectopic pregnancy. The beta HCG levels in the blood can be detected using highly advanced methods which can identify a pregnancy as soon as two days before a woman misses her period. In the older pregnancy kits HCG presence was determined by a urine test but these are not very sensitive and won’t detect the pregnancy as early as a blood test. More modern pregnancy test kits are more sensitive and can detect pregnancy about 2-3 days after missing a period.

The urine test kits are still beneficial since they are less expensive than other test kits and the test can be carried out in the comfort and privacy of home to determine pregnancy. Instructions must be followed in order to ensure that the results are accurate.

Blood tests have the advantage over urine tests in that they would give an actual measurement of the beta HCG level in the blood. This is especially important if there is a need to identify any potential problems with the pregnancy. In order to properly interpret the results another test must be taken within 48-72 hours of the initial test to see if there is any doubling of the HCG beta levels. Once the levels are doubling the pregnancy is progressing as it should. Since every pregnancy is different what really matters is that the numbers are doubling rather than what the actual levels are. Of course the levels will be significantly more in multiple pregnancies and lower if the pregnancy is ectopic or non-viable.

As beneficial as the HCG test is it has one major drawback in that it can only indicate that pregnancy has occurred. It will not provide details on the location of the pregnancy, for instance if the pregnancy is tubal. Early on in the pregnancy HCG beta levels will help doctors monitor the pregnancy but as the pregnancy progresses they will rely more on an ultrasound since they are more accurate and provide an better picture of what is taking place in the uterus.

Expectant fathers also need to be fully aware of the changes too since they might be witness to their formerly sane women becoming unpredictable and moody. Once they understand that hormones are the culprits behind the altered behavior they will be better able to adjust to the changes.

The Link Between Pregnancy and HCG

HCG or the human chorionic gonadotropin hormone is the first hormone to make itself present after conception. As such it is commonly referred to as the announcer of pregnancy. It is this hormone that is identified in home pregnancy kits and lab tests to determine pregnancy. In some special cases the increased levels of hCG can be detected as early as 8 days after conception has occurred. Generally though, it is most present and detectable after eleven days.

If the pregnancy is progressing without any major health complications the levels of hCG in the body of a pregnant woman will almost double every two days for the first 10 weeks of the pregnancy. The major role of hCG in pregnancy is to regulate the production of the other hormones, estrogen and progesterone, until the placenta has developed sufficiently to take over this very important role.

Pregnant women experience the side effects of an increased hCG level very early in the pregnancy. One such side effect is a very sensitive bladder that comes about due to an increased flow of blood to the pelvic region. The increased blood supply to this region prompts the bladder to want to rid itself of even the smallest amount of urine. After the first trimester women do experience some relief from the sensitivity in the bladder but it will return later in the pregnancy as the baby crowds the womb and pushes against the bladder.

Other unpleasant side effects of hCG include nausea and vomiting that is so often present in early pregnancy. These symptoms are commonly labeled with the term “morning sickness” although this term is very misleading since the symptoms can appear any time of the day or night. The nausea, vomiting and queasiness usually make themselves known around week eight to ten when the hCG levels are at their peak. The symptoms will however ease up when the second trimester rolls around.

The levels of hCG in pregnancy will increase and decrease during the course of the pregnancy. It peaks at week nine or ten and decreases slightly around the sixteenth week and thereafter remains constant until birth.

HCG is first detected in the body at 11 to 14 days after conception has occurred. The urine at home pregnancy test that you take measure the levels of hCG in your body and indicates whether or not you are pregnant. HCG is measured in milli-international units per milliliter (mIU/ml).

The HCG levels during the different stages of pregnancy vary a lot. During the first three weeks of pregnancy on average the levels might be between 5-50 mIU/ml. One week later in the fourth week the levels could be anywhere between 5-426. Week five and six the range might be 18-734 and 1,080-56,500 respectively. Women who are not pregnant can have hCG levels of 5.0 mIU/ml and less. For pregnant women the levels are expected to double every two to three days for the first ten weeks of the pregnancy. This indication of doubling is a lot more important that the actual amount of hCG present.

The numbers presented simply means that low hCG levels in the early part of pregnancy do not necessarily mean that there is something wrong by itself. The range of what is considered normal is extensive and even if you fall outside the range it does not mean that something is wrong as long as your doctor detects the doubling of the amounts every few days. If your hCGlevels fail to double then there might be a real cause for concern. The first conclusion that your doctor would arrive at is that there is a possibility of a miscarriage. It could also indicate that you are having an ectopic pregnancy where the embryo is growing in the fallopian tube rather than the uterus where it should be. The final possibility is that you have a blighted ovum where the egg has been fertilized but it remains undeveloped. Although these are not all guaranteed answers the doctors will certainly explore these possibilities.

The presence of low HCG levels early in your pregnancy is no cause to be alarmed. What is normal for one woman might not be for another when it comes to hCG measurements. If your levels are not doubling you should definitely consult with your doctor to make sure that there is nothing wrong. If you are diagnosed with an ectopic pregnancy the doctor will recommend that the developing tissue be removed immediately since it could rupture and endanger your life.

If the hCG levels suddenly drop there is a possibility that you have a blighted ovum and the result would be a miscarriage that effectively deals with this problem. This would occur naturally without any intervention from the doctor.

It is important to monitor your hCG levels during those first crucial months of pregnancy especially if you have a history of miscarriages. The important thing is to not be alarmed by the results. Low hCG levels does not imply that there is something wrong. Any tests that cause concern should be taken to the doctor who will perform further tests to come to a valid conclusion.

What really is hCG?

Human chorionic gonadotropin, commonly referred to as hCG, is a hormone that the body produces in early pregnancy and continues in varying levels throughout its duration. Doctors check the hCG levels to get information on how the pregnancy is progressing.

What are quantitative hCG blood tests?

Quantitative hCG blood tests are used to measure the levels of hCG in a pregnant woman’s blood. For more accuracy your doctor will recommend that you provide two separate blood samples over 2-3 day period.

What hCG levels are considered normal during the different stages of pregnancy?

HCG levels can vary especially in early pregnancy. This is why there is a broad spectrum from what is considered normal at this stage. If symptoms of a miscarriage are present two separate tests will be taken to determine whether the hCG levels are increasing or decreasing. This is why doctors will issue two tests and not one.

What is the reason for the monitoring of hCG doubling time and what is considered normal?

At your first pregnancy appointment your doctor will order two blood samples to be taken two-three days apart to check whether the hCG levels are increasing or decreasing. If the pregnancy is normal the hCG level should double every 2-3 days for the first ten weeks of pregnancy.

Is there cause for concern if the hCH levels rises slowly?

Slow-rising hCG levels might be a sign that there are complications in the pregnancy. The doctor will take further tests or closely monitor the progress to see if there are any changes. In some cases however there is no need to worry since in about 15% of pregnancies the hCG doubling time is a lot slower.

Doesa low hCG level indicate an impending miscarriage?

This all depends on the time of pregnancy and the number of tests taken. If the hCG level is low very early in the pregnancy there is not too much cause for concern. If the hCG level is low in only one test there might also not be any cause for concern. To accurately come to a conclusion doctors need to take two tests on separate days to see whether the hCG level is going up or down.

If my results show that my hCG levels are dropping, does that mean that I am going to miscarry?

If the levels of hCG are falling over time in the first trimester it does mean that a miscarriage is imminent.

Why Do Doctors Order hCG Blood Tests?

Tests to monitor hCG numbers are a routine part of early pregnancy prenatal care. Some doctors use urine based tests to confirm pregnancy and only order blood tests if they need to know more about what is taking place in the pregnancy for instance if there is vaginal bleeding or if the patient complains of any other symptoms associated with miscarriage.

They may also be ordered to determine if the hCG is within a normal range although this can vary widely. Another reason for the tests is to check the hCG doubling times to see if the pregnancy is progressing normally. In this case the tests will be given over a period of 2-3 days to check for increasing hCG numbers.

Getting Prepared for an hCG Blood Test

There is no special preparations necessary before taking an hCG blood test. No fasting or decrease in your fluid intake is necessary since these factors will not affect the blood drawn for the test.

What Are Serial hCG Blood Tests?

Serial hCG blood tests involve the quantitative analysis of blood to determine the hCG numbers over a two to three day period. Early in the pregnancy the levels should increase every 2-3 days. If the doubling time is more than this or if there is a decrease in hCG numbers then this is an indication that something could be wrong. It could be an indication of a possible miscarriage or an ectopic pregnancy.

If you are experience miscarriage symptoms early in the pregnancy the doctor will request serial blood tests in order to get a better idea of what is going on with the pregnancy.

Interpreting the Results

The best person to interpret what your hCG numbers mean is your doctor since what is normal varies from one person to the next. Also single hCG tests, even when the hCG numbers are low, does not really provide much information on how the pregnancy is progressing. Your doctor would compare the results with the other information that he has on your medical history to make a conclusion. Some things he will take into consideration include whether you have had miscarriages in the past and what your current symptoms are.

Even though slow rising hCG levels might indicate problems it is still possible to have a normal pregnancy.

How To Find Out What Your hCG Levels Are?

There are qualitative tests which simply checks for the presence of hCG and quantitative tests which measures what quantity of the hormone that is present in the blood. A qualitative test can be used to determine if conception has taken place while the quantitative test is used to determine how the pregnancy is progressing.

How Do Your hCG Results Mean?

In normal pregnancy your hCG results will double every two days and will eventually slow down as the pregnancy advances. Once the level of hCG levels reaches between 1,200 and 6,000 mIU/ml serum, the hCG usually takes 72-96 hours to double and at 6,000 mIU/ml and above the hCG results would reveal that the time taken to double would extend to as much as four days or more. At this stage there is no real need to continue monitoring hCG levels since the results no longer indicate how well the pregnancy is progressing.

HCG Pregnancy tests

What Are Normal hCG Results?

Since every woman and pregnancy is different is it is pointless to come up with a figure that is normal. Even more than this it is not a good idea to come to conclusions on the state of your pregnancy based on numbers that you believe that are normal. What might be normal for one woman might be very low numbers for you. Additionally different ranges of numbers are associated with each stage of pregnancy. Someone who has not conceived would have hCG results that are less than 5mIU/ml. Newly pregnant women would have results that are in the region of 25mIU/ml and above. If you are planning to take an ultrasound it won’t be able to detect anything until the levels are about 2,000mIU/ml. This level would normally be reached about the fifth week of pregnancy.

How Medications Affect hCG Results

The medication associated with infertility treatments, which contain hCG, will affect the hCG results that you receive after testing. Infertility drugs increase the chances of pregnancy by increasing the natural hCG in the body and thus increasing the chances for getting pregnant. If you are not pregnant the test results will show decreasing hCG results as the hCG introduced into the bloodstream through the medication wears off.

hCG Results in Multiples Pregnancy

If a woman is pregnant with multiples the hcG results will reveal levels that are larger than “normal.” The presence of multiple fetuses increases the volume of hCG in the bloodstream.  If you want to accurately detect the stage of your pregnancy you can do so with your hCG results although ultrasounds would provide a more accurate prediction.

What role does HCG play in pregnancy? HCG plays an important part in the production of progesterone, another hormone which lines the uterus with extra blood vessels and capillaries. This provides a safer and more supportive environment for the growing embryo. Another role of HCG is to protect the fetus from the mother’s own immune system, which may try to reject the baby in the initial trimester of pregnancy, recognizing the fetus’s cells as foreign to the body.

Why is HCG of interest to you, beyond its biological role in the growth of your new baby? HCG levels can serve as a benchmark to alert you to what changes are going on in your body and whether your pregnancy is progressing normally. In fact, it is HCG which urine pregnancy tests measure. HCG levels by themselves don’t prove anything about your baby’s status, and they vary quite a bit from woman to woman. In general though you should expect your HCG levels to double every two to three days. The range of normal levels is quite wide, but the progression should be about the same. After two or three months though the HCG levels will increase more slowly and eventually will plateau for the rest of your pregnancy. There may even be a slight decline just before the plateau; this is normal. If your HCG levels are “abnormally” high, you may also have twins or triplets, but this cannot be determined without additional tests. Sometimes levels are just high for no particular reason, because everybody is different. What you think may be “abnormal” could be quite normal for you.

If your HCG levels aren’t doubling every few days in the early stages of your pregnancy or if they are declining, you should speak to a doctor and ask for additional tests. It’s no cause to panic; you and your baby may both be just fine. It’s always best to make sure though, which is what ultrasound and other medical tests are for. Only these tests can confirm for certain whether things are going smoothly or there might be a problem.

HCG levels are something which are great to keep track of throughout your pregnancy. Just don’t forget that by themselves they indicate nothing for certain, and you will always need to follow up with a more concrete medical test. Have fun keeping track of your pregnancy and good luck!

If the expectant mother is expecting multiples the levels will be much higher and if there are no doubling of the levels it would suggest that there is something wrong with the pregnancy. The possibilities will include either a blighted ovum which will expel itself via a miscarriage or an ectopic pregnancy. A number of tests are used to measure the beta HCG levels in the blood including RIA (radioimmunoassay) , CLIA (chemiluminescent assay) and DELFIA ( fluorescent immunoassay) testing. The tests are so sensitive that positive levels (more than 10 mIU/ml) in the blood might be detectable as soon as teo days after a missed period.

In days gone by the only way to detect the presence of hCG was through urine tests in pregnancy test kits. Today there are some urine pregnancy kits that are very sensitive and can be used to detect a pregnancy as early as 1 to 2 days after missing a period as long as the blood hCG level is about  50 to 100 mIU/ml. The main benefits of urine pregnancy test kits are that they are inexpensive and that the tests can be carried out at home. To ensure that the results are accurate the instructions must be carefully followed. Simple things like urinary tract infections, failure to follow instructions and urine that is diluted can compromise the results.

Blood tests on the other hand are advantageous in that they will measure the actual beta hCG levels in the blood. This is something that can prove to be extremely helpful in detecting and managing any problems that might occur. Most physicians will order a test as early as 16 days into the pregnancy and one will be required 2-3 days after the first test. The levels should double every 2-3 days as the embryo continues to develop. This doubling is an indication that the pregnancy is progressing normally and the opposite is true if there is no increase in the beta hCG levels.

You might experience problems with hCG testing if you were given HCG (human chorionic gonadotropin) injections to induce ovulation. This exogenous HCG is usually excreted within 10 days but it might linger on. It is for this reason that if the results show low beta hCG levels the test would be repeated just to confirm that the levels are increasing. If you are given false positive result due to the hCG injection the levels will decline if you’re not but if you are it will increase.

Although hCG testing has proven to be helpful it’s major drawback is that it confirms pregnancy but it fails to provide details on the location of the pregnancy which may be tubal or ectopic.

A lot of women worry when they think their HCG levels are unusual, for example rising slowly. HCG levels should rise, so that part is fine, but the rate at which it happens should be double every few days. There is a lot of variation though with HCG levels. They aren’t a perfect indicator of what is going on with your body or your fetus, and they can only be used as a general point of reference. Every pregnancy has a wide range of levels which might be present and represent nothing out of the ordinary. Your HCG levels certainly shouldn’t be decreasing; if they are, you should have it checked out immediately as it could indicate a problem. If your HCG levels are doubling every 2-3 days then everything is as it ought to be. If your HCG levels are rising but doing so more slowly than that, you may or may not have a problem.

For some women, slowly rising HCG levels are the readout for a normal, healthy pregnancy. But for others it may be indicative of a problem such as blighted ovum, an upcoming miscarriage, or ectopic pregnancy. If you believe you may have one of these problems you should get it checked out. A blighted ovum is an egg which has been successfully fertilized but doesn’t develop. This usually leads to a miscarriage which can occur naturally without intervention. A miscarriage is heartbreaking, but it will rarely endanger your own life. In the case of ectopic pregnancy though, surgery may be necessary. This is when the embryo grows in the fallopian tube and not your uterus where it belongs. Medical intervention is necessary at this point to save your life.

You can’t go on HCG levels alone to determine whether your pregnancy is normal or not. Even doctors use HCG levels only as a reference to decide whether further testing might be necessary in a given situation. If your levels are slow or decreasing, your doctor will probably order an ultrasound or another test which can give a more definitive answer. If your levels are normal though there is rarely a need to investigate further during the first trimester of your pregnancy since it indicates all is proceeding smoothly.

So if your HCG levels are increasing at a slow rate and it’s making you anxious, ask your doctor to check into it with ultrasound or another technique to give you some peace of mind. But don’t panic, because it could be that nothing is wrong and you have a healthily developing fetus!

HCG levels are first distinguishable approximately two weeks after conception. When you take a urine pregnancy test, it’s HCG which the test is measuring for. All HCG measurements are in milli-international units per milliliter (mIU/ml).

Even as far as average HCG levels go during various stages of pregnancy there is a huge range! In the first three weeks, the average is 5-50 mIU/ml, and in the first four weeks, 5-426. In week five, the average is 18-7,340, and in week 6, 1,080-56,500. In a non-pregnant woman of breeding age, the average is less than 5.0 mIU/ml. HCG levels are expected to double every two to three days. The doubling is more relevant than the actual amount which is present.

What this means is that low levels of HCG in the early stages of pregnancy doesn’t necessarily indicate anything on their own! Again there is a huge range for “average,” and falling outside of that range still may not be particularly relevant, as long as your levels are doubling every few days. If your levels aren’t doubling, then there could be a problem. Sometimes this indicates that a miscarriage is possible, or that you have a blighted ovum or an ectopic pregnancy. An ectopic pregnancy is when the embryo is growing in the fallopian tube instead of in your uterus. A blighted ovum is an egg which has been fertilized, but remains undeveloped. Even that’s not necessarily guaranteed though. You may simply have some kind of an error in your date calculations which is throwing off your interpretation of what you see.

Low HCG levels in early pregnancy aren’t on their own a cause for alarm. “Normal” for your body may not be the same as “normal” for another woman’s body. If your levels aren’t doubling every few days it isn’t a cause to panic, but you should definitely go to the doctor’s office and get it checked out, just to make sure that there isn’t a problem. If by chance you do have an ectopic pregnancy, your life is in danger and you will have to have the developing tissue extracted before you experience a rupture.

What do you do if your HCG levels go up, and then drop? This is another indication you may have a blighted ovum. If you have a blighted ovum you usually can have the miscarriage naturally without any problems.

Monitor your HCG levels, but remember not to take them at face value. They can be a helpful indicator, but in themselves they reveal nothing objective. Hypotheses you create based on HCG levels need to be confirmed by further and more concrete evidence before you can draw any positive conclusions about your pregnancy.
