The Medismart Early Pregnancy Test has been designed to determine pregnancy as early as only 7 days after sexual intercourse. How can this be possible? The MediSmart Early Pregnancy Test uses the highest quality components and measuring processes (membrane, antibody, etc.) to lower the 50 IU HCG (Humanes Choriongonadotropin) cut-off level of most pregnancy testing products down to 20 IU HCG. This major increase in sensitivity makes it possible for the Medismart Early Pregnancy Test to make such early and accurate predictions.
