A false-positive result indicates a pregnancy even though there isn't one. Rarely, the test may detect abnormal, non-pregnancy tissue, which requires follow-up by a doctor. These results are rare because usually only pregnant women produce the hCG hormone.

However, negative results are less reliable. For example, if you do a pregnancy test too early, you could be pregnant, but there may not be enough HCG in your body to give a positive test result. Pregnancy tests vary in their sensitivity (how soon they can detect HCG and what level of HCG needs to be present).

They often take them before or shortly after their first missed period. Although hCG is present in their urine, they have a lower level of the hormone, resulting in a positive pregnancy test with a faint line. These women are pregnant, but they're not far along in the pregnancy.

Pregnancy tests work by checking your urine (pee) for a hormone called human chorionic gonadotropin (HCG). Your body only makes this hormone if you're pregnant. HCG is released when a fertilized egg attaches to the lining of your uterus — when pregnancy begins.

Only urine that contains a sufficient level of hCG can cause the test's dye to stain in a way that shows a positive result. In early pregnancy, there may be very little hCG in the urine, and the positive line may be faint.

How HCG works as a pregnancy test. Many women have very low levels of HCG in their blood and urine when they are not pregnant. HCG tests detect elevated levels. Tests may not detect pregnancy until HCG has risen to a certain level.

Even in a normal intrauterine pregnancy, false negative urine pregnancy results may occur if the urine is very dilute. A negative urine hCG does not definitively rule out ectopic pregnancy, regardless of the date of the last menstrual period.

Finding out whether or not that's happened is as easy as taking an over-the-counter (OTC) pregnancy test. OTC pregnancy tests typically test your urine for a hormone called human chorionic gonadotropin (HCG). HCG is only present if you're pregnant.

If you think you could be pregnant but haven't noticed any symptoms, you still might be. You could just be lucky. Some women sail through their pregnancy feeling on top of the world. Everyone's different and nobody else will have a pregnancy just like yours.

If the test result is negative, you may not be pregnant. However, negative results are less reliable. For example, if you do a pregnancy test too early, you could be pregnant, but there may not be enough HCG in your body to give a positive test result.

Roshan says. "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.

An early test doesn't really answer any questions. It just confirms you don't have any detectable pregnancy hormone in your urine yet. 2﻿ The process of fertilization and implantation takes several days, and a test taken before this process is complete won't be positive.

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).

It is possible to have a positive pregnancy test result and not actually be pregnant – despite many people telling you otherwise. It's called a false positive – and while it's not common – it does happen (and we know it can be seriously disappointing if you're trying to conceive ? )

As a general rule, home pregnancy tests are the best way of finding out if you are pregnant. However, in some rare cases, you may be pregnant, but not have enough HCG in your system – which means you won't get a positive reading.
