Get clear, accurate results with the Leader One Step Pregnancy Test. This easy-to-use diagnostic tool is designed to provide results in just minutes with the convenience of a single step. It works by detecting the presence of Human Chorionic Gonadotropin (hCG), the hormone your body produces during pregnancy. With a sensitive testing tip and a large results window, this test is over 99% accurate when used from the first day of your missed period. The simple "one-step" process means no messy cups or droppers are required—just hold the absorbent tip in your urine stream for a few seconds.
