Is First Response Digital less sensitive?
Results: Using a mixture of hCG, hyperglycosylated hCG and free β-subunit typical for early pregnancy, the sensitivity of the First Response manual and digital tests was 5.5 mIU/mL, while the sensitivities of the EPT and ClearBlue brand manual and digital tests was 22 mIU/mL.

What is the lowest level of hCG detected by First Response?
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.
Is First Response more sensitive than clear blue?

When can 25 mIU be detected?

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 is sensitivity rated in pregnancy tests?
How is Sensitivity Rated in Pregnancy Tests? Sensitivity in pregnancy tests is rated on their ability to detect hCG in urine. Researchers say that by day 8 of pregnancy your body starts to produce hCG. By the 10 th day, hCG levels reach 12 mIU/mL and by day 11, 25 mIU/mL.
What is the most accurate pregnancy test?
According to research, First Response pregnancy tests are the most accurate pregnancy test because they can detect the lowest hCG level. First Response is sensitive enough to detect hCG as low as 6.3 mIU/mL. These types of sensitive pregnancy tests are some of the best pregnancy tests for early detection.
