Differences in tests?

Question

I took a first responsea few days ago with fmu and got a very faint line, but today I tested with a clear blue and I don't really see anything (not fmu). Is it just taking longer for blue dye to read positive or??????

Answer

The chance of a false positive im any test is below 1%
The chance of a false negative on a digital or blue dye is above 70%
Digital and blue dyes require higher levels of hcg to give a positive result.

Answer

Hard to say. A false positive on a FRER is HIGHLY unlikely. Did the line show within the correct time frame? If so I'd say false negative on the clear blue or a chemical (though I hope that's not the case).

Answer

Here is the first response & clearblue comparison, both in time frame
