First Step Pregnancy Test 1s

The First Step Pregnancy Test 1s is a rapid, single‑use home pregnancy test designed to detect a possible pregnancy by measuring the presence of the hormone hCG (human chorionic gonadotropin) in urine. The test is marketed as highly sensitive and able to detect pregnancy as early as about seven days after intercourse. It uses a chromatographic immunoassay to indicate whether hCG levels in urine have risen above a threshold — a rise that typically happens soon after conception begins. The test is simple and convenient to use any time of the day, and provides a result in about five minutes. According to its makers, in laboratory conditions it has a high accuracy rate, comparable to more formal pregnancy testing.
