Modern home pregnancy tests (which use a urine sample to detect the presence of human chorionic gonadotropin or hCG, a hormone produced during pregnancy) are fairly reliable. So most of the time, getting a negative result on a pregnancy test means that you are probably not pregnant.

If you test too early, a test may not pick up enough hCG to turn positive. If you're testing before the day of your expected period, you may see a negative result – even if you're pregnant – if: Your test wasn't sensitive enough for early testing.

"If you do a pregnancy test before you miss your period, the result may be negative with a urine test but positive with a blood test." Early pregnancy tests aren't usually necessary, but they can make a difference for women at higher risk for miscarriage or ectopic pregnancy.

Getting a false-negative pregnancy test because of the hook effect is rare. False-negative test results can happen for many reasons. One older study that tested 27 different kinds of at-home pregnancy tests found that they gave false negatives almost 48 percent of the time.

Could a negative result be wrong? It's possible to get a negative result from a home pregnancy test when you're actually pregnant. This is known as a false-negative.

False Negative Pregnancy Tests In fact, it is possible to have a negative result on a pregnancy test and actually be pregnant. Here is how it works: The goal of a urine pregnancy test is to test the urine for a hormone called hCG (Human Chorionic Gonadotropin). This is the hormone your body produces during pregnancy.

A third reason for a false negative result on a pregnancy test is diluted urine. If you drink a lot of water, it will dilute the hCG in your urine, and could cause you to get a false negative.

A negative pregnancy test does not absolutely rule out pregnancy or ectopic pregnancy; it may simply be too early to detect hCG in the mother's urine or blood.

A negative pregnancy test result means the test hasn't detected hCG in your urine. If your period is very late, or you've skipped your period, and you get a negative result, you are unlikely to be pregnant.

You can get a negative result on your pregnancy test for two reasons: You are not pregnant or you are pregnant, but you tested too early for the pregnancy test you used to pick up the hCG 'pregnancy' hormone in your body.

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.

Traces of the administered hCG may still be in your bloodstream and detectable by a test even if implantation has not occurred. A false negative might occur as a low level of hCG may be undetectable in a urine test despite a pregnancy starting as these are less sensitive than the blood hormone tests we administer.

The tests only turn positive once there is a certain level of the hCG hormone present in your urine: if you test too early, the result might be negative even though you are pregnant. Therefore, if you don't get your period but you had a negative result, test again after two to three days.

Some women get a negative test, and then later test positive for pregnancy. If this happens, believe the positive test. ... If the test is negative, or you continue to get a mix of positive and negative pregnancy tests, it could mean you are having a miscarriage or that your HCG levels are very low. Call your doctor.

Standard urine pregnancy tests will detect the HCG level when it reaches 20-50 milliunits/milliliters. If you take a test too soon (before you've missed your period), the levels of HCG may not be high enough to detect a pregnancy and it could cause a negative result, even though you're actually pregnant.
