e.p.t. - Supporting Women for Decades

Since 1976, e.p.t. has been helping women discover their pregnancies at home, starting as the first FDA-approved test of its kind in the US. The name originally meant “Early Pregnancy Test” but later evolved to “Error Proof Test,” showing how much we value accuracy. Today, we’re still all about giving women reliable answers during life’s biggest moments, with tests that are over 99% accurate.
