Reasons for pregnancy test results going the false route

A lot many of us would have gone on to perform more than one pregnancy test, just to be sure of the fact that one is pregnant. This is taking into consideration that we would be satisfied with taking one test. Now the question if we are crazy or can we rely on the results of a single pregnancy test. Though the general feeling is that 99 % of the time the results are accurate, yet statistics point to the fact that this is rarely the case as it is somewhere between 54 % to 99 %. You need to understand that there are number of reasons why a pregnancy test can be wrong

The reasons for a false negative test

The main reason for it is that the test is being done too soon, or there happens to be little HGG in your urine. The HCG is produced by the placenta and this cannot be detected until and unless the fertilized egg attached to the uterus and this goes on to happen 6 to 12 days after you ovulate. If the pregnancy test is done soon after conception the chances of detection of HCG is a bare minimum.

Ideally, what you should do is to wait for a week and then get the test done again. This is all the more true when you are part of irregular cycles or one is not sure on what is the exact date of their last cycle. Then there is a hook effect which happens when there happens to be too much amount of HCG in your urine. If there is too much of HCG present, the test cannot detect it. If this test is negative and you have missed your last period then it is better to get in touch with a doctor. Most often than not a pregnancy test false negative leads to a situation of molar pregnancy.

The reasons of a false positive test

If the result of the tests turns out to be positive, then you are pregnant for sure. These sorts of false pregnancies are rare, but they are caused by the following reasons.

· The test has not been performed in a proper manner and is due past the expiry date

· The situation of phantom HCG might also occur. This can be detected by a certain amount of HCG which is left from an early miscarriage, the HCG which tends to arise from an infertility treatment and this should be out from your system two weeks after injection. The HCG which tends to arise from molar pregnancy

· It may also arise with the antibodies in the system that goes on to interfere with the antibodies in the test. This situation is not that common and only occurs in case of woman who normally work with animals.

Ideally what should be done is that you should go on to repeat the test once in a week following the same set of instructions.
