There are several tests that test for pregnancy ranging from the home pregnancy test to the other end of the scale which is the pregnancy blood test usually administered by a physician or health care provider.
The test results from home pregnancy tests are private and they take only few minutes. With the help of such early pregnancy tests, early diagnosis of your pregnancy can be discovered and confirmed with a pregnancy blood test. Early pregnancy tests are usually conducted in the home. They test for a hormone called HCG (Human Chorionic Gonadotropin). This is the earliest test of pregnancy since this hormone can be detected in the woman’s blood or urine even before she misses her menstrual period. The early pregnancy tests are carried out in the morning with the first urination.Pregnancy blood tests are more accurate than urine tests. The home pregnancy tests are usually conducted by collecting urine in a cup and using a dipstick to determine if the hormone is present. The dipstick will usually turn a certain color and this can be compared to a chart. Some times the dipstick is a little more high tech and it will give you a + or a – sign. It will depend on the brand or the cost.
