Yes, false negative readings do happen, either from testing too early or from making an error in following the test instructions. They can also arise from using a diluted urine sample and/or from inaccuracies in timing of the test.

It is to be noted that first morning urine is the ideal specimen for pregnancy testing as it contains the highest concentration of HCG, the level of which can differ from one woman to another despite a similar gestational stage.

So, if you suspect you’re pregnant, go see your doctor for a blood pregnancy test no matter what result you get from any home pregnancy test kit.
