Factors That Affect HCG Results In Pregnancy

Human chorionic gonadotropin commonly refered to as hCG, is a hormone that is produced by the placenta during pregnancy. The first traces of hCG can be detected as early as eleven days after conception with some of the more advanced pregnancy test kits or via blood tests.

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.

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.
