How Pregnancy Tests Work

From the earliest moments of conception, your body is already starting to undergo monumental changes. One of the very first is production of the pregnancy hormone, hCG (human Chorionic Gonadotropin), which can be detected in your blood and in your urine.

The amount of hCG in your body increases rapidly. It doubles every 36 to 48 hours as your pregnancy progresses, reaching its peak at eight to ten weeks. Pregnancy tests work by detecting hCG levels in your urine. When a woman's urine comes in contact with the specially treated strip on a pregnancy test stick, results appear within minutes, indicating whether or not hCG, the pregnancy hormone, has been detected.

Some at-home pregnancy tests are unable to detect hCG in urine sooner than the first day of a missed period. Advancements have enabled one at-home pregnancy test to detect hCG 6 days before a missed period1.
FIRST RESPONSE™ Early Result is the ONLY Pregnancy Test that tells you 6 days before your missed period.  For easy-to-read, unmistakable Yes/No results in words, try FIRST RESPONSE Gold™ Digital Pregnancy Test that detects hCG in urine five days before your missed period.2

Pregnancy is truly a life-changing event. Knowing earlier if you are pregnant or not allows you to make important decisions such as adopting healthier lifestyle choices. You can begin taking better care of yourself and your baby sooner, in the critical first stages of your baby's development.
