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. Blood tests measuring hCG levels can also be used to check how long you have been pregnant. Most people can expect their levels to return to a non-pregnant range about 4 - 6 weeks after an abortion.
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.
