How do Early Pregnancy Tests work?

Early pregnancy tests are acutely more sensitive than the standard pregnancy test kits available. The early detection pregnancy test is able to distinguish low levels of the hCG hormone (human chorionic gonadotropin) and detect if a female is pregnant in the early stages even before she has missed her period. During the early stages of pregnancy, the hormone hCG is released in large amounts and multiplies quickly. It is found in the female’s urine.

Most often, a typical home pregnancy test will produce a positive result as soon as the hCG hormone gets to a level of 25mIU within the urine. However, an early detection pregnancy test will produce a positive result once the hCG level gets to a mere 10mIU within the urine which makes it far superior and more sensitive to a regular home test. Using an early detection pregnancy test will reveal a positive result much quicker and can be detected as early as 8 – 10 days following ovulation.

How to use Early Pregnancy Tests

In order to complete an early detection pregnancy test, you simply dip the strip in a sample of urine and wait a few moments for the results. Every pack includes a full set of instructions.

The peak concentration level of hCG hormone is highest first thing in the morning; therefore it’s crucial to test your first pass of urine upon waking to obtain a more accurate test. This way you will achieve a much greater chance of indeed detecting a pregnancy. Throughout the day, the hormone level will diminish and so will your ability to detect how much is in your urine; therefore reducing your chances of discovering whether you are pregnant or not.
