Blood or protein in the urine may cause false-positive pregnancy results. Urine hCG tests may give a false-negative result if the urine is too diluted or if testing is done too soon in the pregnancy. Certain drugs such as diuretics and promethazine (an antihistamine) may cause false-negative urine results.
A false positive test resultâa positive human chorionic gonadotropin (hCG) test result when you are not pregnantâcan occur for a variety of reasons. Most over-the-counter pregnancy tests measure the levels of hCG in a womanâs urine.lood tests can detect hCG at lower levels than urine tests, and therefore can detect a pregnancy earlier. Of course, it is possible for a woman to become pregnant, get a positive test result, and then miscarry. This is known as a chemical pregnancy.
