Home pregnancy tests
These tests can be very useful because they can tell you if you're pregnant in just minutes, with a urine sample taken any time of the day, fewer than two weeks after conception. Home pregnancy tests involve placing urine on a prepared chemical strip and waiting for one or two minutes for the strip to show the result. These tests check for a hormone that is produced in excess amounts during pregnancy known as human chorionic gonadotropin or hCG. hCG levels are normally low in non-pregnant woman. However, with pregnancy, your placenta produces large amounts of the hormone, causing higher amounts of hCG to be secreted in your urine.
Since hCG levels do not rise immediately, depending on how early you are in your pregnancy, a home pregnancy test can show a negative result even though you may actually be pregnant. Ideally, a home pregnancy test should be performed seven to ten days after missing your period in order to ensure a minimal amounts of false negative tests. Also it is important that you follow all the instructions correctly. If you had a negative test but tested yourself less than ten days after the first missed period, wait a few more days and try the test again. When done correctly, home pregnancy tests can be as accurate as urine tests done in a doctor's office or laboratory.
