HCG is a human chorionic gonadotropin, a hormone secreted after
implantation of a fertilized egg. It is one of the most sensitive methods to
check whether a pregnancy is possible.
Range criteria for chorionic gonadotropin in pregnant offspring:
According to the hCG range used by the American pregnancy association for
reference:
Menopause 3-5 weeks - 50 mIU/ml •
4 weeks of menopause: 5-426 mIU/ml •
5 weeks of menopause: 18-7,340 mIU/ml •
6 weeks of menopause: 1,080-56,500 mIU/ml •
7-8 weeks: 7, 650-229,000 mIU/ml •
9-12 weeks of menopause: 25,700-288,000 mIU/ml
13-16 weeks of menopause: 13,300-254,000 mIU/ml •
Menopause 17-24 weeks: 4,060-165,400 mIU/ml •
25-40 weeks of menopause: 3,640-117,000 mIU/ml •
Women with amenorrhea: <9.5 mIU/ml
HCG less than 5mIU/ml is a negative reaction, not a pregnancy, and any
amount more than 25mIU/ml is a positive reaction, a pregnancy.
If you're pregnant, 85 percent of the women double the amount of hCG in
their blood every two or three days; If hCG is not increasing at this rate, that
means the likelihood of pregnancy failure.
Tip: don't rely too much on the hCG number. A normal pregnancy may have a
lower hCG and produce a normal baby.
