Why does the line on positive pregnancy tests fade?
Okay, got it. Is it possible to get a false negative or false positive result on a pregnancy test?
Yes, it is possible to get both false negative and false positive results. False negatives can occur if the test is taken too early or if the urine is too diluted. False positives can occur if the test is not read properly or if there is a medical condition, such as an hCG-secreting tumor, that is causing a falsely positive result.
