The ancient Egyptians had a unique way of proof, if a woman was pregnant or not. Like modern pregnancy testers, they also use a woman’s urine to check if conceive or not. Egyptian doctors urine of women in a grain mixture is poured, if any of sprouted grains, the result was positive, and if none of sprouted grains, was negative. This technique was inaccurate and therefore did not develop further. Over time, scientists came up with many methods of determining pregnancy with little success until the final strip of pregnancy HCG was invented in 1968 by Margaret Crane. Today, women around the world can easily check whether or not they are pregnant by using a pregnancy tester that is readily available at the local pharmacy store. However, doctors prefer that a blood test is obtained to confirm the result.
