What pregnancy tests 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.
What is the sensitivity of an early pregnancy urine test kit?
With most current pregnancy test kits (sensitivity 25 units per litre) urine may reveal positive results 3-4 days after implantation; by 7 days (the time of the expected period) 98% will be positive. A negative result 1 week after the missed period virtually guarantees that the woman is not pregnant.
How sensitive is a 25 mIU ml pregnancy test?
For example, tests claiming 25 mIU/ml sensitivity were declared to be > 99 % accurate from the day of the expected period and capable of detecting pregnancy up to 4 days before the expected period. These tests are likely to be correct, providing the test is always able to detect 25 mIU/ml of hCG in every urine sample.

How much hCG is needed for a positive pregnancy test?
An hCG level of less than 5 mIU/mL is considered negative for pregnancy, and anything above 25 mIU/mL is considered positive for pregnancy. An hCG level between 6 and 24 mIU/mL is considered a grey area, and you’ll likely need to be retested to see if your levels rise to confirm a pregnancy.
How long does it take for hCG to reach 25 mIU?
Urine hCG concentrations reach 10 to 25 mIU/mL by 7 to10 days after conception. Urine pregnancy tests have a sensitivity of 90% to 97% and a specificity of 99% for pregnancy during the first week after a missed menstrual period.
How early can 10 mIU detect pregnancy?
Whereas other tests have a sensitivity of 20 mIU/mL (meaning there needs to be at least 20 mIU/mL of hCG in the urine), our test has a sensitivity level of 10 mIU/mL and can detect the hCG hormone up to five days before your expected period.
