What Could Cause a False Positive on a Pregnancy Test? Normally a blood test or obstetric examination helps to determine a true pregnancy from a false one. Theoretically, a man being injected with HCG could have a positive pregnancy test, even though one would know the man was not pregnant. Other medications may also cause a false positive on a pregnancy test. These include anti-convulsants, medications to treat Parkinson’s disease, certain tranquilizers, and certain diuretics.

False Positive Pregnancy Test ResultsLast updated on Aug 27, 2012by Monica Scott This scenario often occurs in women undergoing fertility treatments which contain hCG, such as hCG shots. The hormone in the drugs may cause the test to read a false positive. To avoid this- ensure that you have allowed enough time for the shot to be completely out of your system before using a pregnancy test. If you are unsure, retest a week or two later and/ or see your doctor for medical advice and testing.

Getting pregnant However, most medications, including antibiotics and birth control pills, don't affect the accuracy of home pregnancy tests. Although rare, it's possible to get a positive result from a home pregnancy test when you're not actually pregnant. This is known as a false-positive. A false-positive might happen if you had a pregnancy loss soon after the fertilized egg attached to your uterine lining (biochemical pregnancy) or you take a pregnancy test too soon after taking a fertility drug that contains HCG.

When you have a urinary tract infection, blood and protein can enter your urine and alter the test results.

The In Vitro Fertilization (IVF) Process: The Embryo Transfer & Pregnancy Testing As tempting as it is, fertility patients are advised not to use home pregnancy tests. Home pregnancy tests can render false results for fertility patients, either negative or positive.

False Positive Pregnancy Test Result and Phantom HCG Pregnancy tests have certain instructions and before you make the diagnosis of a positive pregnancy test make sure that you followed all instructions. Most manufacturers suggest to read their test after 3 minutes and to NOT READ it after 10 minutes. Once you have a negative test after 3-5 minutes THROW OUT the test. Any positive test appearing only well after that time is inaccurate and cannot be considered positive.
