Home Pregnancy Tests
If you think you may be pregnant, a simple test using a small sample of urine can provide the answer.
How do pregnancy tests work?
A urine pregnancy test looks for human chorionic gonadotropin (hCG), a special hormone that is present only when a woman is pregnant. hCG begins to be produced the moment a fertilized egg is implanted into the uterus. After that event, the levels of hCG in the blood double every 2 to 3 days.
What are the advantages of using a home pregnancy test?
Home pregnancy tests are inexpensive, easy to use, private, and require only a few minutes of time to obtain results. Furthermore, the test kits are available in most drug or discount stores and do not require a prescription. According to pregnancy kit manufacturers, most at-home pregnancy tests are 97 to 99 percent accurate when used as instructed.
