A number of factors can cause false positive or negative reading. This article discusses some of the potential causes of a woman getting a false positive pregnancy test read.

Home urine pregnancy test works by detecting the presence of human chorionic gonadotropin or hCG in the urine. This is the hormone of pregnancy, and it was found both in the urine and blood.

Home pregnancy tests vary depending on the brand, and each will be instructions to follow for detailed accuracy.

Some kits require users to put the test stick in his urine stream. Others may use either urine collection cup dip stick pregnancy or to take urine from the pipette to the placement on the test stick.

How to express a positive or negative test result also depends on the brand and may include :.

important, when taking a pregnancy test, a woman must realize that even faint signs plus or line indicates a positive result

However, not all positive pregnancy test means that a woman is pregnant. There were several occasions when the pregnancy test can give false positive readings.

People should talk with their doctor for further evaluation if they receive a positive pregnancy test.

In addition, it is important for a woman to speak with a medical professional if she believes she might be pregnant, but she has received a negative pregnancy test. This is because the further testing may be needed to confirm the true condition.

Below are five possible situations that can cause a woman to have a false positive result on a home pregnancy test.

When you take a home pregnancy test urine, it is important to follow the instructions of this test completely. Each brand has specific instructions, so it is important to read it closely.

Most of the test will prompt the user to read the results within 4-5 minutes to take the test and no more than 10-30 minutes afterwards.

Most urine pregnancy test non-digital will display one line if a woman is not pregnant and two lines if she is pregnant, or plus or minus sign.

If the pregnancy test is read after the recommended time has elapsed, it can lead to what looks like a positive test result. However, in many cases, this is not a positive pregnancy test but the lines left by the evaporation of urine after the recommended time to read the test.

Take a urine pregnancy test at home, following an abortion or miscarriage, may be another reason for false positive results.

After the fertilized eggs implanted into the uterine wall, the body starts secreting the pregnancy hormone hCG. After miscarriage or abortion, hCG levels begin to fall, but only slowly.

Normally, hCG decreased during the period ranging anywhere 9-35 days. The average time frame of about 19 days. Take a pregnancy test in a period of time can result in a false positive test.

At times, a woman may have suffered a miscarriage is incomplete. This condition means that there may be a network of intrauterine pregnancies that continue to produce hCG. If this happens, surgery with dilation and curettage may be necessary to remove the products of conception.

A molar pregnancy or hydatidiform mole is a condition that causes the uterus to grow.

a molar pregnancy is caused by a genetic abnormality at conception and produce a normal pregnancy.

in a complete molar pregnancy, maternal chromosomes are not present, only a father. This leads to no embryo or placental tissue.

Instead, have a partial molar pregnancy the embryo and placenta. However, the embryo has two sets of chromosomes from the father and one set from the mother. This gives the embryo 69 chromosomes instead of the normal 49.

Instead of a normal placenta and embryos, placental tissue at a molar pregnancy develops in a way that resembles a bunch of grapes. This is the result of a mass of small fluid-filled sacs that form, which must be removed by dilatation and curettage.

a woman's hCG levels closely monitored after surgery, to make sure they get back to normal.

At the time,a condition called persistent gestational trophoblastic disease can occur. This is due to the continued growth of the products of conception in the womb molar. This can be a serious medical condition that requires surgery to remove the uterus or.

Women who had a molar pregnancy can still grieved the loss of their pregnancy, together with women who have a miscarriage.

certain medications can cause women to have a false positive pregnancy test.

These medications include those with hCG as an active ingredient, which is often used to treat. Someone who take medication to treat infertility may want to be tested for pregnancy by their doctor.

Most medications and drugs, including alcohol, did not affect the results of a home pregnancy test.

Certain medical conditions can cause hCG woman to ride, even when she is not pregnant. They include:

phantom hCG occurs when specific antibody binds with the molecules in pregnancy testing kits used to detect hCG. Interaction lead testing kits to signal that hCG levels are higher than they actually are.

According to the US Office on Women's Health, a home pregnancy test could be 99 percent accurate when used correctly.

The amount of hCG present in the urine of women increases with time, and accurate results are usually obtained if the test is taken after the missed period.

However, in the vicinity, only hCG levels begin to rise after the first day of a missed period. In these women, the test may not be accurate if done at this time.

Do not use the test right way or check the results later than the recommended time can cause false positive results.

If a person has a positive pregnancy test, it is important to tell your doctor, because they will require further evaluation and testing to confirm and monitor their pregnancies.

If someone believes that they may be pregnant, but the pregnancy test results negatively in their homes, they should talk to a doctor for further guidance.
