How Do Pregnancy Tests Work?



Home pregnancy tests are typically small plastic sticks that are held under a stream of urine. One end of the stick has an absorbent tip that captures urine and directs it inside the test. Pregnancy tests measure levels of a hormone called human chorionic gonadotropin or hCG. This hormone begins to be released as soon as a fertilized egg becomes implanted in the walls of the uterus. The amount of hCG in a woman's body gradually builds up as the placenta begins to develop and the embryo grows. When hCG reaches certain levels, it can be detected by the home pregnancy test. A test will show one symbol if you are pregnant and another symbol if you are not pregnant. Most tests produce results in three to five minutes.

When Should I Use a Pregnancy Test?



In order for hCG to be detected in a urine sample, it must be at adequate levels. As a result, pregnancy tests cannot produce positive readings immediately after conception. The majority of tests are 99 percent accurate when used on the first day of your missed period. Some tests do have the ability to produce positive results a few days before the first day that a woman's menstrual cycle would normally begin; however, their accuracy rate is reduced until the first day of a missed period. If you test before that date and receive a negative result, you might consider retesting if your period does not begin on schedule.

Tips for Choosing a Pregnancy Test



There are many different types of pregnancy tests on the market today, which can make it difficult for women to decide which one to purchase.
  • First, consider whether you need an early result pregnancy test that could detect pregnancy before the first day of a missed period or a standard test.
  • Then, decide whether you wish to purchase a single test or a multi-pack.
  • Next, compare the display windows and symbols, choosing a type that you believe will be easy for you to read.
  • Pregnancy tests may vary in price due to special features like digital displays. You can refine your search to shop by price range using the links at the left.

Important Things to Remember



Pregnancy tests are only effective when used correctly. Even if you have used a pregnancy test in the past, you should read the instructions and follow them carefully to help ensure accuracy. In the event that negative readings persist and menstruation does not occur, see your doctor. If your testing reading is positive, schedule an appointment with an OB-GYN or midwife as soon as possible.
