How Do Home Being pregnant Tests Work?
Home being pregnant tests work by detecting the presence of human chorionic gonadotropin (hCG), a hormone produced during pregnancy. After a fertilized egg attaches to the lining of the uterus, the body begins producing hCG. The levels of this hormone increase rapidly within the early levels of pregnancy, doubling approximately every days.
Most dwelling being pregnant tests are designed to detect hCG in your urine. The test typically entails putting a number of drops of urine on a test strip or immersing the test in a small cup of urine. If hCG is detected, a positive result will appear within the form of a line, a plus sign, or another indicator, depending on the test’s design. If no hCG is detected, the test will point out a negative result.

Not all residence pregnancy tests are created equal when it comes to sensitivity. Some tests are designed to detect lower levels of hCG than others, which means they will detect pregnancy earlier. For instance, some tests claim to provide accurate results as early as 5 to 6 days before a missed period. These tests are normally labeled as “early detection” tests and could also be more sensitive than normal tests.
Nonetheless, even probably the most sensitive tests could not give an accurate end result if the hCG levels in your urine are too low at the time of testing. If you test too early, there’s an opportunity that the quantity of hCG in your system will not be detectable yet, leading to a false-negative result.
Timing of the Test

Ideally, you need to wait at the least one week after a missed period to take the test for the most accurate result. This allows sufficient time for hCG levels to rise to detectable levels. If you cannot wait that long, utilizing an early detection test may improve your possibilities of getting an accurate end result, but keep in mind that testing too early can lead to a false-negative result.
Factors That Can Affect Accuracy
While house being pregnant tests are generally reliable, several factors can influence their accuracy:
Testing Too Early: As mentioned earlier, testing earlier than hCG levels have risen sufficiently can lead to a false-negative result.

Blood tests can detect lower levels of hCG and are typically more accurate than house tests.
Then again, if you happen to receive a negative consequence but still suspect you are pregnant, wait a few days and take another test. Generally, hCG levels might not be high enough to be detected initially. If you happen to continue to get negative results however still do not get your interval, it’s finest to seek the advice of your physician for additional evaluation.
