But obtaining a positive false pregnancy test result can be devastating—especially for people who have difficulty conceiving or are actively trying to become pregnant. The last thing you want is to jump out of joy — just to discover later that you are not pregnant. Of course, getting a positive fake pregnancy test when you are actively trying can be so horrible. Yup, you could probably do it without a panic trip to the ob-gyn, just to learn there was nothing to do. Fortunately, positive false pregnancy tests are rare, but can happen. Here are some of the most common causes. What is a pregnancy test? You have the basic fist: A test tells you if you are pregnant or not. But the details could be a little blurry. Pregnancy tests at home for hCG hormone. HCG is short for human choraline gonadotropin, which the body produces during pregnancy. Just after a fertilized egg joins the uterine lining, the placenta is formed and produces hCG, according to the . A blood test can detect hCG about 11 days after conception, and a urine test can detect it 12 to 14 days after conception, according to , although it varies – some tests can detect a pregnancy even before. A person's HCG level is normally doubled every 72 hours through 8 to 11 weeks of pregnancy. Then it remains consistent and decreases after delivery. How does a pregnancy test work? A home pregnancy test is designed to detect hCG in , explanations. If the hormone is present, it triggers a chemical reaction and test signals that you are pregnant. If the HCG is not present, the test will say that you are not pregnant. In many tests, two lines mean you're pregnant and one line means you're not, but it depends on the test mark. Some tests use more and less signs. Some digital pregnancy tests have a screen that reads clearly "pregnant" or "not pregnant. "It seems simple, doesn't it? As Ina Garten would say, "How easy is that?" Typically, quite easy. Most pregnancy tests at home claim to be about 99 percent accurate, notes. Ultrasounds can usually not detect a pregnancy until a little later in their pregnancy and that's why home tests are so useful. But sometimes, other elements can get into the results of a pregnancy test and tell her she's pregnant when she really doesn't. Causes for a false-positive pregnancy test Here are the most likely reasons you can end with a positive false pregnancy test: If you take a standard test with line indicators, it is important to check the results within the time frame instructed. If you let it sit too long before reading the results, the urine in the test can evaporate and make it look like it has two lines instead of one. "People will often see the evaporation lines as the urine begins to evaporate from the test," says the doctorate, obgion certified by the board, the doctor. That could make the test look like it has a second weak line, which makes it positive, but it really only has one. The best way to avoid this: Read the pregnancy test instructions and follow them exactly. The popular pregnancy test brand, for example, reads users to wait three minutes after taking the test, and then read it as soon as possible. The second most common reason for Dr. Dr. Abdur-Rahman get false positives is because the test is expired, he says. When a test is passed its expiration date, the chemical that detects hCG does not always work as it should, and it is more likely to get a malleche. "The test can expire and the possibility of having a false positive increase," says Dr. Abdur-Rahman. If you take a pregnancy test too soon after taking a medication containing hCG - like some injections that are often part of in vitro fertilization - you might get a false positive."[ This happens with] women who are very motivated and trying to conceive, and often will test early pregnancy and see a positive result, which is obviously very exciting for them initially," says Zev Williams, M.D., associate professor of Obstetrics and Gynaecology and head of the Reproductive Endocrinology and Infertility Division at the Irving Medical Center at Columbia University, SELF. "But it could be the result of the fertility medication they took. It is something that we warn patients about what they have no false hope when they see the test positive. "Most abortions occur in the first 13 weeks of pregnancy, according to ACOG. And, although there are no real statistics, it is estimated that many occur before a person even knows she is pregnant. After giving birth or abortion, hCG may persist in your body for months, says Dr. Williams. A study published in estimates that takes four to six weeks for hCG levels to return to normal after a person suffers a . This is because some of the placenta can be left behind in the body, and can continue to produce hCG for a short period of time. "While there are growing viable placenta cells within women, these tests can be positive," says Dr. Williams. An ectopian pregnancy occurs when a fertilized egg ends up growing outside the uterus — usually in a fallopian tube — instead of the uterus, according to the uterus. That said, an ectopic pregnancy can also occur in other reproductive areas such as ovary or cervix. An ectopian pregnancy is not viable as the embryo is not within the uterus where it can grow and thrive. But the embryo will still produce HCG, which can lead to a positive false pregnancy test. According to the Mayo Clinic, an ectopian pregnancy can be life-threatening. Call your doctor right away if you experience any of the following symptoms: Severe pain in your abdomen or pelvis while you are pregnant (which is out of the ordinary) severe dizziness or dizziness Any other symptoms that are making you feel worried6. You've had an early abortion. We are putting this reason for the last time because it is not technically a cause behind a positive false pregnancy test, but it is still worth covering because many people confuse it with one. You could get your period a few days after a positive pregnancy test and assume that you had a positive false result. However, it might be that you were pregnant, but you had been deceived very early. "It is not that the test is wrong, it was completely accurate when collecting the hormone [hCG]," says Dr. Williams. "Unfortunately, this was not a healthy pregnancy." Doctors refer to this early pregnancy loss as a . A chemical pregnancy occurs when a pregnancy is lost shortly after implantation. People who have a chemical pregnancy often experience bleeding (when they are lost) just at the time of their expected period, so it is easy to assume that they have just had a positive false test result. Next Steps After A False-Positive Test Although most pregnancy test results are accurate, it may be difficult to know immediately if you are dealing with a positive false pregnancy test result. But your ob-gin may perform a blood test to keep your hCG levels under review and clarify any possible pregnancy test error. Dr. Abdur-Rahman says he sees pregnancy tests at home more like "detection tests": a blood test is a diagnostic test that can confirm that he is pregnant. If a blood test confirms that you are pregnant, your ob-gin may continue to monitor HCG levels in your blood to ensure that the pregnancy is developing properly before an ultrasound can reveal more details. And if you get a negative pregnancy test, you know that sometimes it's possible too. If you take a pregnancy test at home too early, you might not pick up the hCG hormone. But, as we have explained above, these hormones must be doubled every 72 hours with a healthy pregnancy. "The more you wait, the more likely you will be to detect pregnancy," says Dr. Williams. Recommend to take another pregnancy test two days later to check it out. Sources:Related:SELF does not provide medical advice, diagnosis or treatment.
