Why do you have to test with morning urine. What if it's still morning BUT it's your second void of the day?

I guess the reason you have to do it in the morning is beacuase there is some hormone that usually is the strongest in the morning. I have taken pregancys tests on my second usrine and also in the evening. I guess it depends on how far you are.

Hello there, I found this answer for you at this site... (First Morning Urine and Pregnancy Test Accuracy)

Should I use "first morning urine" to test for pregnancy?

To increase the accuracy - or more precisely to increase the possibility of receiving a positive test result earlier - it is advised to use a first morning sample when testing for pregnancy. Why? Unless you have urinated in the middle of the night, first morning urine should exhibit a higher concentration of the pregnancy hormone, hCG. This means you can get an accurate result sooner than with other samples collected during the day or evening.


Hope this helps! :)

Hello Found another good site for you to check out...

Here is what they said here,

The reason that most pregnancy tests recommend first morning urine is that this urine typically contains the highest concentration of hCG, the pregnancy hormone. However, if you work nights or your sleep is interrupted by bathroom breaks, you may have the most concentrated urine at this time.
You can recreate first morning urine by not using the bathroom for at least four hours. You must also not drink more than your normal amount or you can dilute your urine.
( I thought this was interesting and I didn't know this was possible so I guess you learn something new everyday... LOL)
Typically after the fourth of fifth week of pregnancy your levels of hCG are high enough withouthaving to use first morning urine.

It does not matter if you urinate on the stick or in a cup.
