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

Most house pregnancy tests are designed to detect hCG in your urine. The test typically entails 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.

Not all residence being pregnant tests are created equal when it involves sensitivity. Some tests are designed to detect lower levels of hCG than others, which means they can detect being pregnant earlier. As an illustration, some tests claim to provide accurate outcomes as early as five to six days earlier than a missed period. These tests are often labeled as “early detection” tests and could also be more sensitive than normal tests.

However, even essentially the most sensitive tests could not give an accurate end result if the hCG levels in your urine are too low on the time of testing.

If you cannot wait that long, using an early detection test could improve your chances of getting an accurate end result, however keep in mind that testing too early can lead to a false-negative result.

However, if you receive a negative end result however still suspect you are pregnant, wait a couple of days and take one other test. Generally, hCG levels may not be high sufficient to be detected initially. In case you proceed to get negative outcomes however still do not get your interval, it’s greatest to seek the advice of your physician for additional evaluation.
