After a fertilized egg attaches to the lining of the uterus, the body begins producing hCG. The levels of this hormone enhance quickly within the early levels of pregnancy, doubling approximately every two days.

Most home pregnancy tests are designed to detect hCG in your urine. The test typically includes inserting a couple of drops of urine on a test strip or immersing the test in a small cup of urine. If hCG is detected, a positive consequence will seem in the form of a line, a plus sign, or some other indicator, depending on the test’s design.

Some tests are designed to detect lower levels of hCG than others, which means they’ll detect being pregnant earlier. For example, some tests declare to provide accurate results as early as five to six days earlier than a missed period. These tests are usually labeled as “early detection” tests and may be more sensitive than commonplace tests.

Nevertheless, even the most sensitive tests may not give an accurate result if the hCG levels in your urine are too low on the time of testing. When you test too early, there’s a chance that the amount of hCG in your system will not be detectable yet, leading to a false-negative result.

Ideally, you need to wait no less than one week after a missed period to take the test for probably the most accurate result. This allows enough time for hCG levels to rise to detectable levels. If you can’t wait that long, utilizing an early detection test may improve your possibilities of getting an accurate outcome, but keep in mind that testing too early can lead to a false-negative result.

Factors That Can Affect Accuracy
