Guideline to hCG levels during pregnancy:
hCG levels in weeks from LMP (gestational age)* :
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
Non-pregnant females: <5.0 mIU/ml
Postmenopausal females: <9.5 mIU/ml
* These numbers are just a GUIDELINE-- every woman’s level of hCG can rise differently. It
is not necessarily the level that matters but rather the change in the level.
What can a low hCG level mean?
A low hCG level can mean any number of things and should be rechecked within 48-72 hours to see
how the level is changing. A low hCG level could indicate:
What can a high hCG level mean?
A high level of hCG can also mean a number of things and should be rechecked within 48-72 hours
to evaluate changes in the level. A high hCG level can indicate:
Should my hCG level be checked routinely?
It is not common for doctors to routinely check your hCG levels unless you are showing signs of
a possible problem. A health care provider may recheck your levels if you are bleeding, experiencing severe
cramping, or have a history of miscarriage.
What can I expect of my hCG levels after a pregnancy
Most women can expect their levels to return to a non-pregnant range about 4 - 6 weeks after a
pregnancy loss has occurred. This can differentiate by how the loss occurred (spontaneous miscarriage, D & C
procedure, abortion, natural delivery) and how high the levels were at the time of the loss. Health care providers
usually will continue to test hCG levels after a pregnancy loss to ensure they return back to <5.0
Can anything interfere with my hCG levels?
Nothing should interfere with an hCG level except medications that contain hCG. These
medications are often used in fertility treatments, and your health care provider should advise you on how they may
affect a test. All other medications such as antibiotics, pain relievers, contraception or other hormone
medications should not have any effect on a test that measures hCG.
