How much hCG does a home test detect?

For example, a 99 percent detection rate means a test can detect hCG 99 percent of the time on the day a woman misses her period. These statistics also assume that women are testing at the optimal time, following all instructions, and fully understanding how to interpret the results.

Which pregnancy test can detect the lowest amount of hCG?

One kit, the First Response Early Result Pregnancy Test, emerged as the most reliable and sensitive test. “It detected hCG at concentrations as low as 6.5 mIU/ml (thousandths of an International Unit per milliliter) – that’s almost sensitive enough to detect any pregnancy soon after implantation,” CR wrote.

Can you measure hCG levels at home?

Home pregnancy tests often work by detecting hCG in your urine. It’s worth knowing that non-pregnant women and healthy men also have low levels of hCG. Normally, hCG levels would be less than 5 mIU/mL and less than 2 mIU/mL respectively for these groups.

At what level can hCG be detected?

hCG is a hormone produced by your placenta when you are pregnant. It appears shortly after the embryo attaches to the wall of the uterus. If you are pregnant, this hormone increases very rapidly. If you have a 28 day menstrual cycle, you can detect hCG in your urine 12-15 days after ovulation.

How long does it take for hCG to show in urine?

hCG levels can usually be detected in the urine about 10 days after conception. If you take a urine pregnancy test fewer than 10 days after conception, the at-home tests might give a “false negative” response. This means it will show that you are not pregnant when you actually are.
