What are the human chorionic gonadotropin (hCG) levels during pregnancy?

HCG is a hormone produced by the placenta. If you are pregnant, it is detectable in your urine. Most people can expect their levels to return to a non-pregnant range about 4 - 6 weeks after an abortion.

More information: 

The human chorionic gonadotropin (hCG) is a “chemical created by the trophoblast tissue, tissue typically found in early embryos and which will eventually be part of the placenta.” The hCG levels in weeks from last menstrual period:

3 weeks LMP: 5 - 50 mIU/ml

4 weeks LMP: 5 - 426 mIU/ml

5 weeks LMP: 18 - 7,340 mIU/ml

6 weeks LMP: 1,080 - 56,500 mIU/ml

7 - 8 weeks LMP: 7, 650 - 229,000 mIU/ml

9 - 12 weeks LMP: 25,700 - 288,000 mIU/ml

13 - 16 weeks LMP: 13,300 - 254,000 mIU/ml

17 - 24 weeks LMP: 4,060 - 165,400 mIU/ml

25 - 40 weeks LMP: 3,640 - 117,000 mIU/ml

These numbers are just an indication, every person’s level of hCG can rise differently.  HCG can also be measured in ng/ml, which should be multiplied by 10 to get a number comparable with mIU/ml.
