Can too much urine cause a false positive pregnancy test?

Does the amount of urine affect a pregnancy test?

Can too much urine on a pregnancy test cause a faint line?

A very faint line may also occur if the urine is too diluted to detect hCG. Drinking a large amount of fluid can dilute the urine and skew the results. If a faint line becomes a negative test result the second time around, it could be the result of a very early miscarriage in the first few days and weeks of pregnancy.

What happens if you leave pregnancy test in urine too long?

You might want to take your mind off the nervous wait, but don’t wander off and forget; leaving the test ‘cooking’ for too long can give a false positive result. The reason for this is due to the urine evaporating if left for too long; it can leave a faint line which can be mistaken as a positive test.

Why do I keep getting faint positives?

What causes faint positive lines on a pregnancy test? The strength of the positive test line depends on how much hCG is in your urine. If the line is faint, it usually means that the hCG level is low. One reason why hCG levels may be low could be because you’re still very early into your pregnancy.
