Frequent question: How sensitive is the First Response Digital Pregnancy Test?

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 level of hCG does FIRST RESPONSE Digital detect?

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.

How sensitive are digital pregnancy tests?

Whereas some at-home digital pregnancy tests have a sensitivity of 20 mIU/mL (meaning there needs to be at least 20 mIU/mL of hCG in the urine), the Natalist test has a sensitivity level of 10 mIU/mL, making it more sensitive.

How accurate is the FIRST RESPONSE digital pregnancy test?

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.

Can a digital pregnancy test be wrong?

So, digital tests take the guesswork out of analyzing a pregnancy test, but they are not necessarily more accurate. Ross personally recommends non-digital tests. Moreover, there’s the cost to consider. Even the most expensive tests have the potential to be inaccurate if they’re taken too soon.

Can I be 5 weeks pregnant and still test negative?

Even if you did miss your period but it hasn’t been at least a couple of weeks since you conceived, you could still get a “false negative.” That’s because you need a certain level of a hormone called HCG (human chorionic gonadotropin) in your urine for the test to work.

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.

Can you be pregnant with low hCG?

Even if a complication associated with low hCG levels occurs, such as a miscarriage or an ectopic pregnancy, this does not mean that someone will be unable to get pregnant again or that their fertility is compromised. A successful pregnancy is still possible with low hCG levels.

How many days after implantation does hCG rise?

If you are pregnant, your body needs time to develop detectable levels of HCG. This typically takes seven to 12 days after successful implantation of an egg.
