Human Chorionic Gonadotrophin – hCG

The most common test used to detect a pregnancy in the very early weeks uses hCG.

The hCG hormone starts to be released into the woman’s blood stream soon after the baby implants into the lining of her uterus at about 8 to 12 days after conception. The hCG blood level will initially start off very low (5 mIU/ml), but then rapidly increase, doubling every 2 to 3 days, so that within a few days, to a week or so the hCG level becomes high enough to be detected in the woman’s urine, at about 50 to 80 mIU/ml. Once this level is achieved, a urine pregnancy test will show as being ‘positive’.
