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

If no hCG is detected, the test will indicate a negative result.
Accuracy of Home Pregnancy Tests
The accuracy of a house pregnancy test largely depends on factors: the sensitivity of the test and the timing of while you take it.
Sensitivity of the Test
Not all house being pregnant tests are created equal when it comes to sensitivity. Some tests are designed to detect lower levels of hCG than others, which means they can detect being pregnant earlier. For instance, some tests declare to provide accurate results as early as five to six days earlier than a missed period. These tests are normally labeled as “early detection” tests and may be more sensitive than standard tests.
Nevertheless, even probably the most sensitive tests may not give an accurate outcome if the hCG levels in your urine are too low on the time of testing. If you happen to test too early, there’s an opportunity that the quantity of hCG in your system will not be detectable but, leading to a false-negative result.
Timing of the Test

Ideally, you should wait at least 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 cannot wait that long, utilizing an early detection test could improve your possibilities of getting an accurate outcome, however keep in mind that testing too early can lead to a false-negative result.

However, in case you receive a negative outcome but still suspect you’re pregnant, wait a few days and take one other test. Sometimes, hCG levels won’t be high enough to be detected initially. If you proceed to get negative results however still don’t get your period, it’s greatest to consult your physician for further evaluation.
