What is borderline pregnancy?

A borderline result is generated by some assays when the hCG level is between 5 and 25 mIU/mL. Samples reported as borderline are considered indeterminate, and clinicians should request a repeat test within 48 to 72 hours or obtain a quantitative serum hCG.

What is the hCG level at 1 week?

The placenta starts to produce HCG once the sperm fertilises the egg, therefore it usually takes around two weeks for the levels to be high enough to be detected by a pregnancy test. Average hCG levels: Less than 10 U/L in non-pregnant women. 10 to 25 U/L for a ‘borderline’ pregnancy result.

At what hCG level will I miscarry?

When you miscarry (and also anytime you give birth), your body no longer produces hCG. Your levels will ultimately go back to 0 mIU/mL. In fact, anything less than 5 mIU/mL is “negative,” so effectively, 1 to 4 mIU/mL is also considered “zero” by doctors.
