Test Errors A false negative can also happen due to test error. If you wait too long to read the results, you may get a false negative. That said, false positives are more common with reading a test too late. Make sure you follow the directions of your particular pregnancy test.

You might get a false-negative pregnancy test for other reasons. Some at-home pregnancy tests aren't as sensitive to hCG as others. Or you may take a test too early. It takes time for the hCG hormone to appear in your urine.

There are some medical conditions that can lead to you seeing a false positive pregnancy test result. The most likely reason is blood or protein in your urine. Blood can be the result of having a urinary tract infection. The presence of protein is more serious; this indicates kidney problems.

A false positive can be the result of the fact that in many fertility treatments, hCG is given to “trigger” ovulation and may remain in the blood. A false negative might occur because a low level of hCG may be undetectable in a urine test despite a pregnancy starting.

A negative hCG result means that it is unlikely that a woman is pregnant. However, tests performed too early in a pregnancy, before there is a significant hCG level, may give false-negative results. The test may be repeated in one week if there is a strong possibility of pregnancy.

False positive pregnancy test result – reasons you might get one. As what happened with New_here above, a pregnancy may initially be detected by an early pregnancy test, which will give you a positive result. But then, when you test again at a later time, you get a negative result.

False negative tests are common. In fact, many women get false negative tests before they get a positive. This is because the body's HCG levels have not yet risen sufficiently high to indicate that a woman is pregnant. In many cases, a woman will later get a positive test if she just waits a few days.

A positive test result is almost certainly correct. A negative result is less reliable. If you get a negative result and still think you're pregnant, wait a few days and try again. Speak to your GP if you get a negative result after a second test but your period hasn't arrived.

Another common reason for getting a false negative is not having enough hCG in the urine you test. Early on in pregnancy, you can dilute the hormone concentration in your urine if you drink a lot of water before testing. This is more likely to happen in very early pregnancy when you take the test later in the day.

Yes, it is possible. Getting a negative result doesn't mean you're not pregnant, it may just mean your hCG levels are not high enough for the test to detect the hormone in your urine. ... Also, if you're testing very early, your test may only detect hCG in your urine in the morning when it's most concentrated.

Most home pregnancy tests are reliable, for example Clearblue's tests have an accuracy of over 99% from the day you expect your period, and while it's possible a test showing a negative result is wrong, particularly if you're testing early, getting a false positive is extremely rare.

They're not foolproof, however. It is possible to get a positive result when you're not actually pregnant, which is called a false-positive. If you've been looking forward to a positive pregnancy test result, a false-positive is disappointing. The good news is they're rare.

There may be many different reasons for a negative pregnancy test after a missed period. You may be dealing with an undiagnosed medical condition, such as polycystic ovary syndrome, or it could be a lifestyle issue, such as extreme stress.

A pregnancy test kit is rarely wrong. It is more than 99 per cent accurate. Thus, if your test is negative, it means that you are not pregnant; However, if you are very early in your pregnancy and the test is done far too early, there could be an insufficient amount of urine hCG for the test to detect.

It's possible to have a positive pregnancy test even if you aren't technically pregnant. This is called a false positive. It's sometimes caused by a chemical pregnancy. A chemical pregnancy occurs if a fertilized egg, known as the embryo, is unable to implant, or grow, very early on.

If you take a pregnancy test after your period is late and get a negative result, you're unlikely to be pregnant. Home pregnancy tests are very accurate — about 99 percent — but a false negative is still possible. Try taking another pregnancy test in a day or two to double check.

Not Believing Positive Test Results If you are not pregnant, a false positive pregnancy test result is unlikely. The more likely explanation is that you had a chemical pregnancy (which produces enough hCG to turn a pregnancy test positive but miscarries shortly after) or a very early miscarriage.
