Placental hCG immunohistochemistry and serum free-Beta-hCG.
Concentrations of free beta-hCG and PAPP-A were expressed in multiples of the median (MOM) for gestational age. We compared the levels of both analytes in 73 SGA pregnancies (birth weight below the fifth percentile) with those in 292 normal controls, who were matched for gestational age, maternal age, parity, maternal weight, and smoking habits. We also compared the levels in 87 pregnancies.
You can use the calculator above to calculate the doubling time of two beta hCG samples by entering the values of the blood tests and the number of days between the tests. The hCG levels will usually double approximately every 48 hours ( 2 days) for the first four weeks of pregnancy. As pregnancy progresses the doubling time increases. By 6 to 7 weeks gestation beta hCG levels may take as long.
HCG (Human Chorionic Gonadotropin) is often called the pregnancy hormone because it is made by cells formed in the placenta, which nourishes the egg after it has been fertilized and becomes attached to the uterine wall. Levels can first be detected by a blood test about 11 days after conception and about 12-14 days after conception by a urine test.
HCG level testing is usually carried out to determine a woman's pregnancy health status. Better known as the pregnancy hormone, HCG hormone levels can be confirmed by a clinical test performed on blood and urine samples. This beta or HCG levels has always been shown to have a doubling effect on the next faces of a pregnancy. However, to many women, the HCG anomalous level stir anxiety.

Hi ladies, for those that had the blood test part of the nuchal (ds) test what was you Papp-a result (in mom) and also your free beta hCG (also in mom) result if you don't mind me asking. Would just like to get an average of the ladies on here as mine hasnt been explained to me properly but has affected my adjusted trisomy 21 risk.
Should the beta-hCG level be lower than 50, you will be retested several times to monitor the progress of hCG levels and make sure that the pregnancy is developing as it should. If you need to undergo IVF to become a mother, we recommend that you generate your Fertility Report now.
