On the way to achieving today’s super-simple, one-piece pregnancy tests that give results in two or three minutes, women needed to spend many years playing amateur chemist with test tubes, then waiting a very tense two hours for a result (assuming they performed the test perfectly).
Over the years, the amount of time you needed to wait decreased, but the overall simplicity wasn’t on par with what we have today. Here a look back at the evolution of home pregnancy tests!
What some of the first home pregnancy test kits looked like (1970s)
EPT (Early Pregnancy Test): March 1978
The E.P.T. In-Home Early Pregnancy Test is a private little revolution any woman can easily buy at her drugstore.
It is highly accurate. Millions of women today in 13 European countries use this testing method. Now its high accuracy rate has been verified here in America by doctors who clinically confirmed the results of tests performed by women themselves in their own homes.
That means you can confidently do this easy pregnancy test yourself — privately — right at home without waiting for appointments or delays. That simple difference is the result of many years of costly research. And it’s worth every penny.
At last, early knowledge of pregnancy belongs easily and accurately to us all. It’s simple. Fast. And there is no risk, no physical danger whatever, in doing it, because a sample of your first morning urine is all that’s needed for the test.
As soon as you become pregnant, your body starts to produce a special hormone HCG. Starting on the 9th day after the date you expected your menstrual period to begin, there should be sufficient concentration of HCG in your urine to give an accurate reading of pregnancy. And that’s all there is to it. Follow the test directions with care, and three drops of urine can tell you quickly and easily what you want to know.
If you get a positive reading, you can assume you are pregnant. Such positive pregnancy readings in our clinical tests proved to be 97% accurate. If your reading is negative, your overdue period should begin soon. If a week passes and you still have not started menstruating, you should take a second E.P.T. test because there may not have been sufficient HCG in your urine at the time of the first test, or you may have miscalculated your period. Negative readings on a first test are about 80% accurate; on repeat testing one week later they are 91% accurate. If your second test result is still negative and your period has not begun, we urge you to consult your doctor as soon as possible.
E.P.T. is very simple to do, but it is important that you follow the instructions carefully to insure an accurate reading.
E.P.T. Early Pregnancy Test gives women new power — the power of time to help control the quality of their pregnancies. The first 60 days are critical in fetal development. Improper nutrition, cigarettes, alcohol, even commonly used household medications can be harmful in these crucial first 60 days before most women even know for sure that they ore pregnant. Now with E.P.T., you can know. Now, when you call your doctor, you have the results of your test to report. And time is on your side at last.
