Possible quality issues
The E.P.T. Digital Pregnancy Test, formerly known as E.P.T. Certainty, is a reliable home pregnancy test that works best on or after the day of a missed period, not five days before as the manufacturer claims. It's highly accurate when used closer to the start of an expected period, and the "pregnant" and "not pregnant" results are clear and easy to read.
Best four days later. Independent studies show that the E.P.T. Digital Pregnancy test is 100 percent accurate four days after a missed period. While the manufacturer claims it's 99 percent accurate the day of a missed period, study results indicate that it's only about 68 percent accurate on that day. Users find it to be most accurate at 15 days past ovulation, about the time a period is expected to begin in an average 28-day menstrual cycle. Some women complain of getting different results from the same pack of two tests on the same day.
Not ideal for early testing. The manufacturer says the E.P.T. Digital Pregnancy Test can detect human chorionic gonadotropin (hCG) levels as low as 25 mIU/ml. However, one independent test shows it can detect levels as low as 2.9 mIU/ml in a low percentage of cases. E.P.T. recommends using the test on the first day of a missed period, adding that results can be obtained as early as five days before that day. What isn't mentioned is that the test correctly confirms pregnancy only 5 percent of the time at that five-day mark; most users will receive a false negative.
Words give definitive results. The E.P.T. Digital Pregnancy Test indicates pregnancy with the words "pregnant" or "not pregnant." Consumers say it's "fun" to see the word "pregnant," but it fades quickly so they can't show it off or save it as a keepsake.
The test is activated by either urinating directly on the stick for five seconds, or dipping it for 20 seconds into urine collected in a clean, dry cup. An hourglass timer flashes to show the test is working and to count off the three minutes until the test can be read. Numerous users complain about quality issues, saying the test never activated or they got a book symbol directing them back to the instructions.
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. E.P.T. Digital Pregnancy Test claims to be "over 99% accurate from the day of your expected period" but study findings dispute that, saying the test is only about 68 percent accurate on the day of a missed period. It's 100 percent accurate four days after a missed period.
