I am assuming you are referring to a urine pregnancy test which tests for Beta hCG. There are also blood tests, which are more specific, for pregnancy. The urine beta hCG test may be positive for other reasons than pregnancy. Certain cancers of the testicles and the ovary are diseases that can provide a positive pregnancy test. Also, a lot of blood or protein in the urine can give a false positive on a pregnancy test. There are also some medications that have been reported to cause false positives such as some anti-convulsants and anti-parkinson medications. Overall, though, the urine pregnancy test is very accurate. Any female who tests positive on a urine pregnancy test should arrange for an appointment to see a physician for follow-up.

You took two pregnancy test and both say positive and lately you been having mild pain in your lower stomach could this be an infection or your pregnant and you not really late yet with your period?

If you had two positive pregnancy tests, then you are more than likely pregnant. Your body produces a hormone when you are pregnant that is only present during pregnancy thus showing positive tests. You should see your doctor about the pain, you could have something else going on. Pain is the body's way of telling you something isn't right and it shouldn't be ignored especially if you are pregnant. You are probably pregnant. On rare occasions you can encounter a false positive due to improper testing, expired pregnancy tests, rare medical conditions such as certain types of cancer, evaporation lines, a recent pregnancy or a chemical pregnancy.


How do you challenge the lab results in false positive?

I would look at your hcg levels from the report. An hCG level of less than 5mIU/ml is considered negative for pregnancy, and anything above 25mIU/ml is considered positive for pregnancy. out of curiosity, why would you challenge? Are you certain you are not pregnant?

On rare occasions you can encounter a false positive due to improper testing, expired pregnancy tests, rare medical conditions such as certain types of cancer, evaporation lines, a recent pregnancy or a chemical pregnancy. But if it did say pregnant, I would call your OB/GYN and tell them that you took a pregnancy test and it said positive and you need to make an appointment. They will then confirm your pregnancy with a blood test and possibly and ultrasound depending upon how far along you may be. You will need to be prepared to answer questions about when your last period was and related questions.
