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.

Both tests detect pregnancy by noticing a hormone called human chorionic gonadotropin (hCG) which is also commonly called the âpregnancy hormoneâ because it is created soon after the embryo has attached itself to the uterine lining in the womb.
