Velocit can be used to detect pregnancy as early as the missed day of periods. In some women though, the levels of hCG are not detectable so early in the pregnancy. If the test is negative, you can repeat test after 72 hours. hCG or Human Chorionic Gonadotropin is a hormone that appears in the urine when a woman is pregnant approximately 20 days after her last menstrual period. This pregnancy hormone level then rises rapidly reaching a peak level by 8-12 weeks of gestation. It is advisable to wait a couple of days after missing period, before performing the test. This will help avoid a falsely negative test. For optimal detection of pregnancy, first urine sample of the day is preferred. However, randomly collected urine sample may also be used. Fresh urine sample is desirable for optimum results of the test.
