Can pregnancy tests be wrong? Causes of incorrect results

One of the most popular methods of determining pregnancy is a special test, but is its accuracy as high as producers claim. We can say for sure that in some cases there may be false negative and false positive results, while the second option is extremely rare.

Let us consider in more detail whether pregnancy tests can be mistaken and what errors depend on.

To begin with, cheap tests have a lower accuracy and quite often at very early times they simply do not notice the increase in the level of the hormone. So if you decide to check for a pregnancy before the delay, it's better to take tests at a higher price, where the sensitivity is higher.

Now we know if pregnancy tests can be wrong, but it's worth to clarify the reasons for this.

Taking medication (for example, "Pregnil" or "Profazi") can show a false positive result. Therefore, if you undergo treatment, then wait at least two weeks before doing the tests.

An incorrect positive result can be caused by any diseases of the reproductive system.

It's time to find out if pregnancy tests can be wrong in the negative. As we already know, in this area this analysis misfires much more often, and the reasons are not so intimidating:

- too short a period of pregnancy;

- incorrect operation of the test;

- the delayed test;

- the presence of kidney disease.

There are several other reasons why you see incorrect results, but we have found out whether pregnancy tests can lie. The answer in this case is obvious: "They can not." If you purchased a quality test and did everything right, then the error is minimal. Now briefly indicate additional reasons, because of which the result is shifted in one direction or another. Note that such situations are extremely rare, and there are no reasons for concern, in most cases.

Miscarriage

If at the early stage of pregnancy you have a spontaneous interruption, then the test can show a negative result. Be sure to consult a doctor if you have pain or bleeding.

Ectopic pregnancy

To define this diagnosis it is possible only on survey or at US. Because of the incorrect level of hCG in the body, the test shows the wrong result.

Tumor

Also, can pregnancy tests fail in the event of any neoplasms. Unfortunately, this is the case when the positive result is false, and instead of pregnancy, a tumor develops. This disease increases the level of hCG, which determines pregnancy, but in this case there are symptoms such as bleeding, vomiting.

We examined in detail whether the test could be wrong. As can be seen from the above, the causes of incorrect results are either diseases or incorrect use. Follow the instructions on the packaging and purchase the tests that are designed for your intended time. So, if it is stated that the result will be accurate, starting from a few days of delay, then it is not worth using it until it comes.
