7 reasons for a false positive pregnancy test result

Home pregnancy tests are a common tool in pregnancy detection. Valid home pregnancy tests may be very accurate, but they are not error-free.

These pregnancy tests have their positive and negative points, which we will mention in the rest of this article... Stay with GCORP LLC.

Pregnancy tests

Most pregnancy tests are urine strips that are placed in the urine stream to detect the hormone human chorionic gonadotropin (hCG). This hormone is secreted at the beginning of pregnancy.

(In this article, we have answered 138 common questions related to pregnancy)

Some pregnancy tests can detect hCG early in pregnancy.

False positive and negative results occur for various reasons... It should be remembered that if the pregnancy test is positive, the person should go to the doctor to start primary care during pregnancy.

The cause of false positive home tests

1... containschemical

It is possible that a person is not pregnant during the term, but the result of the pregnancy test is positive, in which case it is called a false positive.

This sometimes happens due to chemical pregnancy... Chemical pregnancy happens when the fertilized egg or sperm cannot implant or grow in the early stages for various reasons.

Premature pregnancy loss is not because a person has done something on purpose, but may be caused by problems inside the uterus, such as:

  • Fibroma
  • Scar tissue (scar)
  • Congenital disorders of the uterus that cause an irregular shape of the uterus

Low levels of certain hormones, such as progesterone, reduce the chance of implantation and embryo development.

Some of the reasons for the chemical burden are unknown.

Chemical pregnancy seems to be very common, but it is usually not diagnosed unless a pregnancy test is done.... The wrong results of the initial experiments tire the human spirit.

For this reason, it is recommended that a person do a home pregnancy test up to a week after the delay in menstruation.

Sometimes the implantation of the fertilized egg is done outside the main cavity of the uterus, which causes an ectopic pregnancy.

Usually, an ectopic pregnancy occurs when the fertilized egg remains stationary in the fallopian tube as it travels to the uterus. This type of ectopic pregnancy is also called a tubal pregnancy.

The following may lead to an ectopic pregnancy:

  • Scar tissue or inflammation in the fallopian tube
  • Abnormal shape of fallopian tube
  • History of uterine infection

Ectopic pregnancy may occur in the cervix, ovary or abdominal cavity.

ectopic pregnancy cannot continue as a normal pregnancy.. In this pregnancy, the sperm cannot survive, because there is no place for it to grow and develop outside the uterus.

Even if the embryo is implanted in the wrong place, it can still produce the hormone hCG, which causes a false positive in the home pregnancy test.

ectopic pregnancy is considered an emergency.....if not treated, the person will be injured and experience heavy bleeding or loss of genital organs.

Symptoms of ectopic pregnancy include the following:

  • Nausea and chest pain, which are also normal symptoms of pregnancy
  • Severe wave of pain in the abdomen, pelvis, shoulder or neck
  • Severe pain in one side of the abdomen
  • Mild to heavy vaginal spotting or bleeding
  • Dizziness or fainting
  • Pressure on the rectum

If a person suspects an ectopic pregnancy, they should see a doctor immediately.

3.... self-abortion or intentional abortion

It is possible that after an abortion, either spontaneous or intentional, the pregnancy test may still be positive.

During pregnancy and with the growth of the fetus, the level of the hormone hCG increases... so that it doubles every few days and reaches its peak around the tenth week.... When the pregnancy ends, the level of this hormone decreases during a gradual process.

Up to six weeks after the end of pregnancy, human chorionic gonadotropin remains in a person's blood and urine. As long as the level of this hormone has not reached the level of pregnancy, there is a possibility of a false positive test result.

If the miscarriage is spontaneous and sudden, all the tissues related to the pregnancy may not be removed from the body, which causes the hCG hormone level to remain high.

In such cases, a minor surgery called dilatation and curettage (D&C) is often required to remove the remaining tissue.

4.... user error

Home pregnancy tests are not infallible like anything else in life.... You should follow the test instructions carefully and check the expiration date before use.

Despite such care, there is still the possibility of error... One of the most common mistakes is to perform this test early in the cycle, which causes the result to be false negative or false positive.

This test should not be performed when the urine is diluted due to excessive fluid intake, but should be performed when the urine is very concentrated, such as in the morning when the person wakes up.

The strip should be placed in the stream of urine for a certain period of time. It is better to set the time on a timer or phone to determine how long the strip is placed in the stream of urine.

When one is waiting for the answer of the test, one can use the timer... It is also important to check the results in a certain period of time.

5... line evaporation

Sometimes the evaporated line is confused with a positive pregnancy test result.... In some home pregnancy tests, two lines are seen when hCG is detected and one line is seen when this hormone is not detected.

Usually these lines are light colored like pink, red or blue....sometimes the second line is lighter indicating the beginning of pregnancy or it may be an evaporated line.

If the line is completely colorless, it is probably a vapor line.

Evaporation lines may appear in the test after complete evaporation of the urine.... Sometimes these lines are caused by hormonal levels and do not indicate pregnancy.

The best way to correctly diagnose a vaporized line is to perform the test exactly at the specified time and according to the instructions.

6... taking some medicines

It is possible that fertility drugs were prescribed to a person who was under the supervision of a doctor in order to get pregnant.

One of these drugs is injection of the synthetic hormone hCG, which is sold under the following brand names:

  • Novarel
  • Pregnyl
  • Ovidrel
  • Prophasy

The hCG vaccine helps the follicles release mature eggs, which can cause a false positive reading on a home pregnancy test, especially when the test is taken too soon.

Other drugs can also cause a false positive pregnancy test result, some of which are:

  • Anti-anxiety medications, such as diazepam (Valium) or alprozolam (Xanax)
  • antipsychotics such as clozapine or chlorpromazine
  • Anticonvulsants such as phenobarbital and other barbiturates Parkinson's disease medications, including bromocriptine (Parlodel)
  • diuretics such as furosemide (Lasix, Diuscreen)
  • Antihistamines, including promethazine
  • Methadone (Dolphin)

7... Conditions Special Medical

Rarely, some special medical conditions cause a false positive home pregnancy test result. These conditions are:

  • Urinary tract infection
  • Kidney disease that causes blood or white blood cells in the urine
  • Ovarian cysts, especially corpus luteum cysts or luteal cysts
  • More dangerous diseases such as ovarian cancer
  • Pituitary problems (very rare)

The pregnancy test is positive, what should I do now?

If the result of the home pregnancy test is positive, the person should refer to a gynecologist and obstetrician to prescribe a urine or blood test and confirm the results and monitor the level of the human placental gonadotropin hormone.

Vaginal ultrasound may also be used to examine the gestational sac to confirm the normal course of pregnancy.

If the person's test result is false positive, he can go to the doctor to make sure it is correct, and if he finds out that he is not pregnant, it may be good news for him!.. (What can a gynecologist help with pregnancy?. Read in this article!)

If a person is very excited after seeing the initial results of the test, the news of not being pregnant may be very sad for him.

It should be noted that if the result of the test is false positive, it is not a sign that the person cannot get pregnant.

If a person has been trying to get pregnant for some time and has not succeeded, especially at the age of 35, they should see an infertility specialist.

Also, there are groups that support a person in this way, and in this case, you can be inspired and gain knowledge from other women who have had such a problem.

Going to a psychotherapist, counseling with a psychologist or family members and talking to trusted friends in this field can be useful for a person.

Final speech

False positive results of pregnancy have many reasons and symptoms, and you should not be happy or sad immediately after seeing a positive result... it has a different emotional burden for everyone.... Also, after this incident, you should be very careful about your health and be under the supervision of a doctor unless the problem is with the test tool.
