When it comes to getting a home pregnancy test, the moment you do it and the state in which your body is are the two basic aspects to obtain a reliable result. False negatives are very common in this type of test, but you should know that from time to time, also the opposite case is presented, a false positive that can change our world for some hours and that, after gynecological check, ends up being a mere fantasy. But why does this happen? In this post, we will have a look at what can cause a false positive pregnancy test and how to avoid those causes.
Fertility Treatments or Weight Loss
The increase of the hormone chorionic gonadotropin or hCG in our organism does not always have to correspond to a pregnancy, and in fact, there are cases in which there is no gestation and yet the test detects its traces. This usually occurs in women who are subjected to fertility treatments in which the doctor administers the hormone hCG by injection, therefore, the same will be present in the body without the need for an ongoing pregnancy. This type of hormone can also be given in weight loss treatments, so it is important to make sure that you are not getting it Fruits
Pollution of Urine
Changes in the concentration of urine that are generated due to the intake of diuretics and even the certain medications can affect the pregnancy test, producing false negatives. Likewise, when urine is contaminated with chemicals such as soap or blood, altered results can also occur. If you collect a sample of urine in a container for use in the test, it is important that it is properly sterilized and it has no traces of any soap or detergent.
Presence of an Embryonic Pregnancy
As explained above, a certain number of days must elapse before hCG is withdrawn and pregnancy is detected. The experts recommend that to do a pregnancy test properly, it should be at least a week late, however, many market tests promise results without even if there is delay, which is a perfect choice for the most anxious ones.
The problem is that this type of test can effectively detect a chemical pregnancy i.e. when the egg has been fertilized, but it is possible that the embryo never develops, which is known as anembryonic pregnancy. This means that despite elevated hormone levels, there is no real gestation, the placenta is formed, but the placenta is empty.
In these cases, the woman can present all the symptoms of the pregnancy, nevertheless to realize the embryo is not detected. Between the tenth and twelfth weeks of putative gestation, the symptoms begin to diminish and the woman must expel placenta spontaneously or through a medical intervention. The cause of this condition is not clearly known, although it is thought to be due to the chromosomal defects that make the embryo never form.
