Pregnancy kits come in all shapes and sizes . What they all have in common is that they are fairly easy to use. Basically, you urinate into a container and follow the instructions about what to do next. Usually, the test results occur in a matter of minutes. Sometimes, it’s good to take a back-up test, particularly if you suspect the test is positive, but it turns up negative (called a false negative; there is also a false positive). A kit is not infallible; it can be wrong.
Personally, I panicked every time I took a pregnancy test mostly because I freaked out that I would do something wrong . Sometimes, I coerced my husband into helping, but usually the directions were simple and easy to follow. There are even pictures if you really get confused. Sometimes, there are two tests in a kit, so if anything goes wrong, you have a backup
FALSE NEGATIVE OR FALSE POSITIVE :
Pay attention because this can get confusing. A false negative means that the pregnancy test indicated the test was negative (you aren't pregnant), but, in fact, it isn't really negative, it’s really positive (you are pregnant). A false positive is the reverse (totally confusing, I know).Any test that you can do on yourself has a false positive and a false negative rate. The manufacturers try to design a test to pick up the entire spectrum of possibilities from everyone who is normal to those who are abnormal. Unfortunately, making any test sensitive to everyone is impossible. For example, if you lower the test to pick up an abnormality, you may pick up a lot of false positives. When you design a test to rule out a problem (for example, you want it to come back negative in most instances), you will have a few false positives. Scientists try to minimize these instances, but they can’t ever eliminate them, so they use a bell-shaped curve.
The upshot of this information for you is that if you know you’re pregnant because your body is telling you something that the test doesn't, then repeat the test. Eventually, it should turn out positive; or preferably, have your doctor do the test. It’s rare that the doctor will have a problem with the test, but it is possible.
