If you are wondering whether or not you might be pregnant, you may be on the verge of heading off to the drug store to make the purchase of a home pregnancy test. For many women in the 21st century, the home pregnancy test has become the most important tool through which they ultimate determine whether or not they are pregnant. If you are considering the purchase and use of a home pregnancy test, there are some facts and factors that you will want to keep in mind.

The first thing that you need to appreciate when it comes to home pregnancy tests is that there are a variety of different products on the market today. Generally speaking, these home pregnancy tests rely on the same “system" to ascertain if a woman is pregnant. However, these tests have varying ways of displaying or conveying this information to a user of the test product itself.

What home pregnancy tests technically are doing is working to detect the presence of a certain type of hormone in your system, human chorionic gondotropin or hCG for short. hCG is a hormone created by the placenta and it can be detected in the urine or blood and is present when a woman is pregnant. If this hormone is detected by a home pregnancy test, the test will indicate that a woman is pregnant.

In this day and age home pregnancy tests have become extremely accurate. Indeed, the typical home pregnancy test proves to provide accurate results virtually 99% of the time. (Some tests do prove more accurate than others; however, the vast majority of home pregnancy tests are not far off this mark.)

There generally are two ways in which a home pregnancy test can be used. First, there are tests in which you dip the test stick or strip into your urine. Second, there are tests in which you urinate directly on the test stick itself.

You need to carefully read all instructions accompanying the test, Normally, a home pregnancy test takes about three minutes after it was exposed to urine until your results will be available. You really will want to “walk away" from the test stick or strip during this time period or it will seem like the longest three minutes of your life.

Home pregnancy tests have different mechanisms through which test results are provided. Some use symbols such as a + and – sign. Still other tests actually spell out the words “pregnant" and “not pregnant." Other tests utilize a color scheme.

Home pregnancy tests that are available today are relatively inexpensive. There can be some price differences but they are not normally that significant. Again, typical home pregnancy tests have about the same accuracy rate as one another.

If you get a positive result from a home pregnancy test, you will want to make an appointment with your doctor as soon as possible. Your doctor will confirm your test results. At that juncture, your doctor will begin planning with your course or prenatal care and related matters. Prenatal care is a crucial element to ensuring that you have a smooth pregnancy, that you remain healthy and that you give birth to a healthy baby when all is said and done.
