Pregnancy Test: What Can Cause a False Positive Result?

Especially annoying if you have problems getting pregnant or on the contrary that you fear a unplanned pregnancythe announcement of a Pregnancy test false positive can be devastating. Because when women who don’t want a child right away don’t turn out to be pregnant while they wait to find out the truth, they can be in intense psychological distress. For those who dream of becoming a mother, hope is crumbling.

Although relatively rare the false positive can happen for many reasons. However, you should know that it is only possible to get a false positive result from a pregnancy test urine, sold in pharmacies and supermarkets. That blood tests they are infallible.

A recent pregnancy can make the test positive

Whether carried to term or terminated by miscarriage or voluntary termination, pregnancy leaves trace amounts of hCG (human chorionic gonadotropin). These traces remain in the body for up to 6 weeks after a miscarriage and several months after pregnancy. In addition, by doing it too quickly, it is possible to get a positive pregnancy test afterwards, when in reality there is no longer any pregnancy or no effective pregnancy in the body. However, it is common for a miscarriage to occur even before a woman realizes it was her pregnant.

Fertility treatments can bias a pregnancy test

If you take a pregnancy test too soon after taking it hCG hormone drug(e.g. specific daily injections to stimulate ovulation for a in vitro fertilization) it is possible to get a false positive result. While the temptation to take a test is great, it’s better to back off and do a blood test after day 10 of conception, which is more likely to give reliable results than disappointment.

The presence of ovarian cysts can lead to a false positive

This affects very few women and especially women with polycystic ovary syndrome (PCOS). When this happens, the ovaries produce more androgen hormone than normal, which can affect the development and release of the egg during childbirth. menstrual cycle. Exactly when egg cells mature and should be released for possible fertilization, cysts develop instead. If they produce the hCG hormone, then they can Fake pregnancy test.

These pathologies that distort pregnancy tests

Aside from ovarian cysts, there are some rare medical cases where a pregnancy test can come back positive if hCG hormone levels tend to rise even though you are not actually pregnant:

  • kidney or bowel disease
  • gastric ulcer
  • liver cirrhosis
  • Certain types of cancer: Germ cell tumors of the ovaries, liver, stomach, pancreas, lung, breast or skin cancer
  • Hormonal disorders related to menopause.

Notice that regular cannabis users often also have above-average hCG levels.

These situations are not considered false alarms

Sometimes the pregnancy test shows a positive result, but you are not actually pregnant. And yet, strictly speaking, he made no mistake. There are several explanations for this.

We’re talking about a chemical pregnancy in the event of one very early spontaneous miscarriagebecause it takes place right after embryo implantationn such that no ultrasound would be able to detect a fetus. The urine test can detect an increase in hCG hormone levels and the test result is therefore positive.

This also applies to the case pregnancy molar toothwhat a denotes complication of fetal development during fertilization (all genetic material from the mother is lost). Instead of an embryo, we get a birthmark (a group of cells that will develop into a cyst) but which still produces hCG hormones.

  • ectopic pregnancy

The latter gives a positive result even without a viable pregnancy. The fertilized egg does not nest in the uterus, but in the fallopian tubes and its development is halted due to space constraints.

Attention : Make sure you use your pregnancy test under the right conditions, i.e. by following the manufacturer’s instructions. Make sure that the expiry date has not expired and read the result within the specified time, as the reading could be falsified if it is exceeded. If in doubt, consult your GP or gynecologist and have a blood test done to confirm your urine pregnancy test results.
