Over 99% accurate from the day of your expected period (Over 99% accurate at detecting typical pregnancy hormone levels. Note that hormone levels vary. See leaflet).
Results 5 days before missed period.
The E.P.T. Certainty 1-Step Pregnancy Test can be used up to 4 days before your expected period, which is 5 days sooner than waiting until you miss your period to test.
However, the distributor of E.P.T. Certainty 1-Step recommends waiting until the day of your expected period for more accurate results.
If you want to test earlier, keep in mind that levels of the pregnancy hormone vary greatly, which makes testing earlier less reliable.
If you test early and get a negative result, the distributor of E.P.T. Certainty 1-Step recommends retesting on the day of your expected period.
