Will a pregnancy test work if urine is diluted?
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.
How do pregnancy tests work with urine?
