False positive pregnancy - Oct 14

False positive pregnancy test before and after your period


The confirmation of pregnancy for women can arouse mixed responses in them as it is the most awaited news for some and a threatening one for others. Both categories of women anxiously wait before the result appears on the pregnancy test kit. Mayo clinic states that results from the home pregnancy kits are 99 % accurate. However, the lower percentile of the results is inaccurate and can disappoint or overwhelm the anxious women with happiness with their incorrect results. What makes these kits go wrong when they are claimed to be extremely accurate in ruling out pregnancy?

Early miscarriage: You may have tested with a positive pregnancy result. However, you get your period following the test. This may be an early miscarriage. According to health experts, majority of 70% of the conceptions are miscarriages. Most of the women do not even realize that they are pregnant and the period they got is nothing but the debris of a miscarriage. However, for those who await pregnancy, this can be devastating.

Fertility medications can be blamed: To understand this, one may need to understand the simple concept behind the test kit. The placenta releases a hormone called Human Chorionic Gonadotropin (HCG) once the egg is implanted in the uterus. The amount of this hormone released multiplies within days and results are more accurate once the HCG is found in the urine.

If you are too enthusiastic in taking a pregnancy test quickly after taking the fertility pills containing the pregnancy hormone HCG, it may lead to an incorrect positive. Those who are on fertility drugs are often suggested by the medical professionals to wait for a while before checking it on a strip.

Residual HCG post a miscarriage or a delivery: Four to six weeks is normally the threshold before which the HCG still exists in the body after a delivery or a miscarriage. Seldom, it happens that a placenta is left in the body to produce the HCG. Till the placenta cells grow in the uterus, the test can lead to a positive result.

Test sits too long: If you follow the instructions of a standard pregnancy test, it will seek your attention in the stipulated time frame. If you make the test sit for longer time before going through the results, the urine on the strip evaporates to appear as two lines instead of one. But it is actually one and the result is negative. In such cases, go for another test immediately and look out for the result in the stipulated time frame.

Expired kit: There is a possibility that the kit you are using to check pregnancy may be past its expiry date. The chemical that reads the HCG may fade away with time leading to an incorrect result. Check the expiry date of the kit before you purchase it to increase the accuracy level.

It is always suggested by the healthcare experts to visit a doctor as soon as you get a positive result on the home pregnancy kit to doubly confirm the same via a check-up. A blood test will be performed to investigate the HCG in your body and it cannot fool you. It may be an agreeable fact that you wait anxiously to know that you are pregnant, but a little patience can get you accurate results.
