Can pregnancy test be negative if urine is diluted?

A third reason for a false negative result on a pregnancy test is diluted urine. If you drink a lot of water, it will dilute the hCG in your urine, and could cause you to get a false negative. Test your urine again upon rising in the morning, as this urine will have the most concentrated amounts of hCG.

Can diluted Pee affect pregnancy test?

Don’t drink too much water, or any liquid, before taking a pregnancy test. Excess fluids can impact the accuracy of the test results, so if your urine is diluted or pale yellow, hold off on taking a test. Diluted urine tends to also have diluted hCG levels which can skew the test results.

Can drinking diluted pregnancy test?

Yes, it’s important not to drink too much of any liquid including water or alcohol before you take a pregnancy test. It’s better to wait until you naturally need to pass urine. This way, you’ll avoid diluting your level of pregnancy hormone and getting a false ‘Not Pregnant’ result.

Can a pregnancy test come up negative if I didn’t pee enough? A false negative on a home pregnancy test is possible, but extremely unlikely. As long as your urine got on the test’s absorbent strip, it should be accurate. You can always take another test if you’re worried you might have missed.

What happens if you put water on a pregnancy test instead of urine?

Presumably, water will give a negative result (we hope!), but you still can’t then add your urine to the strip as well. If you reuse a strip that has gotten wet — either with water or urine and even if it’s dried — you may get a false positive. That’s because as an HPT dries, an evaporation line can appear.

Does clear Pee mean you’re pregnant?

Drinking water—or any fluids—can, in fact, affect the results of an at-home urine pregnancy test, especially when taken very early in the pregnancy. When your urine becomes diluted by drinking lots of fluids, it takes on a pale yellow or clear color, and the urine concentration of hCG becomes lower.
