Ideally, it is best to wait a minimum of one week after a missed period to take the test for probably the most accurate result. This permits sufficient time for hCG levels to rise to detectable levels. If you cannot wait that long, using an early detection test may improve your chances of getting an accurate end result, however keep in mind that testing too early can lead to a false-negative result.

Sometimes, hCG levels may not be high enough to be detected initially. In the event you proceed to get negative results however still don’t get your interval, it’s greatest to seek the advice of your physician for additional evaluation.
