E.P.T., which stands for early pregnancy test, has the distinction of being the first in-home pregnancy test. Back then, just being able to determine pregnancy without a trip to the doctor was a revolution. Nowadays women are looking for a combination of early detection and accuracy, something that E.P.T. doesn't deliver as reliably as other brands.
Best well after missed period. Independent studies show that the E.P.T. Pregnancy Test is 100 percent accurate four days after a missed period. While it claims to be 99 percent accurate the day of an expected period, study results indicate that it's only about 53 percent accurate on that day. Users find it to be most accurate at 20 days past ovulation, about four to six days after a period is expected to begin in an average 28-day menstrual cycle. The control indicator is consistent, but can be quite light.
Not great for early testing. The manufacturer says the E.P.T. Pregnancy Test can detect human chorionic gonadotropin (hCG) levels as low as 25 mIU/ml. However, one independent test reports that it can detect levels as low as 2.9 mIU/ml in a low percentage of cases. E.P.T. recommends that the test be used on the first day of a missed period, adding that results can be obtained as early as five days before a missed period. What isn't said is that at that five-day mark, it correctly confirms pregnancy only five percent of the time; most users will receive a false negative.
Results may be hard to read. The E.P.T. Pregnancy Test indicates pregnancy with a plus sign or a negative result with a minus sign, but the plus sign can be quite faint. Many users say the plus sign is clearly visible even before the test is activated, which causes confusion. Even fans of the test say the lines tend to be blurry and streaky.
1. Clinical Chemistry
Review Credibility: Very Good This clinical study evaluates the urine samples of 120 known pregnant women to confirm the claims of early pregnancy detection of six tests. The manual E.P.T. Pregnancy Test claims to be "over 99% accurate from the day of your expected period." Study findings dispute that, however, saying it's only about 53 percent accurate on the day of a missed period. It's 100 percent accurate four days after a missed period.
