It may surprise you to learn that the earliest records of a urine-based pregnancy test date all the way back to ancient Egypt! A papyrus was discovered describing how a woman who suspected she was pregnant urinated on wheat and barley seeds. After doing this over a few days, if the barley grew, it meant a male child was on the way, and if the wheat sprouted, a female child would be born. If nothing grew, the woman was not pregnant. This theory was actually tested in 1963 and found to be accurate 70 percent of the time, probably because of elevated levels of estrogen.

It wouldn’t be until 1978 that the first home, (e.p.t.) was ready for use. Taking two hours to perform, this pregnancy test gave correct positive results 97 percent of the time. Finally, in the early 21st century, a digital home pregnancy test that took three minutes to administer and was 99 percent accurate became available. Today, about 20 different brands of pregnancy tests are on the market. They are inexpensive and readily available at most grocery and drug stores with no prescription. Many health centers also have them available at no cost.
