Pregnancy (Home) > Pregnancy Test > Home Pregnancy Test 2 Why Your Home Pregnancy Test May give a False PositiveWhen you follow all the directions that come with your home pregnancy test, you will rarely get a false positive. However, there are times when this can occur. The following article will explain some of the reasons why. hCGhCG is the hormone the placenta produces that shows up in the urine during pregnancy. It is often the first indication of pregnancy and more of it is present in the first urine of the morning which is why women are advised to use that urine in the home pregnancy test. Reading the Test at the Wrong TimeOnce you've read the results of your home pregnancy test discard it and move on. No matter how much you stare at it, those initial results are not going to change. If you're not sure how to interpret the results check the package insert that came with your home pregnancy test. Even though it's not the results that change, going back and reading the test again may make the test look positive, especially if it's the kind of home pregnancy test that has a line for a positive result. This is an Evaporation line and it is known to surface after the test sits there for awhile but it is not an indication of pregnancy. Chemical PregnancyThis happens when a fertilized egg actually attaches itself to the uterus just enough to produce hCG but then for reasons unknown stops developing. This happens to about 30-50% of all fertilized eggs and always has. The only reason it is noticed now is because of the increased sensitivity of the home pregnancy test. So while this happened in years past, no one realized it because that process wasn't identified as a positive result. With today's ultra sensitive home pregnancy tests that are capable of showing a positive result with a minute amount of hCG present it's easier to get a false positive result. Using Fertility DrugsThe only drugs that can cause a home pregnancy test to give a false positive result are the ones that contain the hormone hCG, the same one that is produced by the placenta during pregnancy. Fertility drugs are the only drugs that contain hCG so check with your doctor to determine if your fertility drug contains it. If you receive injections containing hCG, wait a week or two after your last injection before taking a home pregnancy test. If you believe you're pregnant, you should follow up with your physician as soon as possible.
