How common are false positive results?

False positive results are rare; in almost all cases a positive result means that you are pregnant. It may be possible for a false positive result to appear if you are taking fertility drugs or you have done the test incorrectly; fertility drugs often cause HCG to be present in the urine, which the test then detects. Many tests now have an indicator which tells you whether or not you have done the test correctly. It is advisable to do at least two tests.
