can a urine pregnancy test detect an ectopic pregnancy?
9957

Serious urinary tract infections (with high levels of WBC, RBC and nitrite) can occasionally cause a false positive pregnancy test result. Ectopic pregnancies typically produce lower levels of hCG than normal preganancies. This will be accentuated by the dilution effect in urine.
