Two Types of Pregnancy Tests
Most hopeful moms-to-be want to know if they are pregnant. In most cases, you can know for sure as soon as one week after conception. When implantation occurs, the developing placenta begins to produce the hormone HCG (human chorionic gonadotropin). This hormone is detectable by the different types of pregnancy tests as early as one week after conception in your blood and 7 to 10 days after conception in your urine.
The most common types of pregnancy tests are urine tests. Urine tests can be performed in your doctor’s office or at home (if you follow the directions on a home pregnancy kit). A very early test may register negative if your body has not yet produced enough HCG to be detected. A repeat test a few days or a week later may come out positive. By the way, a home pregnancy test is nearly 100 percent positive within 7 to 10 days after conception. Whether your test registers positive or negative, if you think you are pregnant, take care of yourself and your baby as if you were pregnant.
A few drops of blood can let you know if you are pregnant as early as one week after conception. This blood test is performed in your doctor’s office or a laboratory. Within a day or two, you will have the final results. The test is nearly 100 percent accurate, depending on no laboratory error.
