These earliest home tests were more accurate for positive results than for negative, and required two hours before results could be read. Evolution of Prenatal Testing. These advances are the result of new or improved methods for acquiring data about the fetus, and new or improved abilities to interpret that data. These advances mean that more information about the fetuss anatomy, genetic make-up, and health can be available today than ever before, often earlier in pregnancy.
