Question

Minimum hcg level that a urine pregnancy test can detect is?

Answer 1

hCG can be detected in urine or blood after implantation, which occurs six to twelve days after fertilization. Quantitative blood (serum beta) tests can detect hCG levels as low as 1 mIU/mL, while urine test strips have published detection thresholds of 10 mIU/mL to 100 mIU/mL, depending on the brand.

Answer 2

Answer:

Bookshelf Urine hCG testing is qualitative, reporting a positive or negative result. The assays detect hCG levels typically starting at 20 to 50 (reportedly as low as 6.3 to 12.5)[19] mIU/mL, corresponding to levels at approximately 4 weeks post-conception. Serum assays can measure beta-hCG as low as 1 to 2 mIU/mL.
