There aren't many false positive pregnancy tests.
The test is looking for (HCG) Human chorionic gonadotropin which is a peptide hormone produced in pregnancy, that is made by the embryo soon after conception.
Since the hormone is made by the embryo it is had to have a positive test from a woman who is not pregnant.
A false positive result on a pregnancy test means that while the test may have said that you are pregnant, you really aren't. False positives are usually caused by old/faulty tests, incorrect reading or use of the test, or by an under lying health condition.
However, home pregnancy tests are more likely to give you a false negative than a false positive.
Well I think you may be a little confused here, there is no type of drug test that is called a "false positive test". However a drug test can be false positive. This means that it shows that a person has done drugs that they have never done (or not done recently enough to show up on the test). For example if an individual had never done cocaine but was on certain medications a drug test for cocaine use could come up positive even though it shouldn't.

A list of things about as long as your arm. Included are such benign drugs as advil, aleve, Motrin, Bayer Select Pain Relief Formula...basically, go to the pain reliever shelf in the drugstore.
