Levels of hCG in pregnancy

Human Chorionic Ganadotropin (hCG) is a hormone that can be detected in the urine and blood of humans. This hormone increases during pregnancy so it is common to measure the rise in level using Home Pregnancy Tests ( or HPTs, which measure hCG levels in the urine) or a hCG Beta test (which measures hCG levels in the blood serum). The hCG Beta is much more sensitive then the Home Pregnancy Test and you can usually get a positive result much earlier with a blood test than with the HPTs.

Usually the reference values for hCG Beta are as follows:

Men: less than 5.0 mIU/ml - Normal

Women: Non -pregnant - less than 5.0 mIU/ml - Negative/normal

*Borderline - Between 5.0 to 25.0 mIU/ml (you could be pregnant)

*Positive - Higher than 25.0 mIU/ml

(*) These are values within the first week and few days after conception.

When you are pregnant the level of hCG increases and usually doubles every two to three days. It then reaches a maximum level by the second or third month of pregnancy, followed by a decrease occurring in the third trimester.

Here are typical hCG Beta values in pregnant women up to 22 days post-retrieval (DPR) or days post-ovulation (DPO).

DPR or DPO Amount of hCG in mIU/ml

10 5 - 50

12 10 - 100

14 20 - 200

16 40 - 400

18 70 - 800

20 140 - 1600

22 180 - 3200

Here are the hCG Beta values given by the number of weeks after ovulation:

after the 1st week and 2 days 5.0 to 50.0 mUI/ml

Between 1st and 2nd week 5.0 to 500.0 mUI/ml

Between 2nd and 3rd week 100.0 to 5,000.0 mUI/ml

Between 3rd and 4th week 500.0 to 10,000.0 mUI/ml

Between 4th and 5th week 1,000.0 to 50,000.0 mUI/ml

Between 5th and 6th week 10,000.0 to 100,000.0 mUI/ml

Between 6th and 8th week 15,000.0 to 200,000.0 mUI/ml

Between 8th and 12th week 10,000.0 to 100,000.0 mUI/ml

Note: The levels of hCG for pregnant women with twins or more are usually higher than the values above, which represent the typical values for just one baby.
