Presense Early Pregnancy Test Strip, Pack of 1’s

Presence Early Pregnancy test strip is designed for early determination of pregnancy, which can be used up to 4 days before expected period. Developed with leading- edge technology for highest accuracy in home tests. The strip detects the hCG (Human Chorionic Gonadotropin) hormone that appears in the urine of a pregnant woman from the first days of conception. Though hCG levels are very low at first, the level rises rapidly and predictably in the first weeks of pregnancy. The earliest you can test with the ultra sensitive tests currently available is 4 days before your missed period.
