False Positive Rexall Pregnancy Test. Since 1978, when pregnancy tests first appeared on the market, they have undergone continuous improvements that now allow them to be more accurate than ever. In fact, most tests are now more than 99 percent accurate in their results.
Pregnancy test accuracy is typically expressed in terms of percentages. For example, the pregnancy tests sold at Early-Pregnancy-Tests.com have a stated accuracy level that exceeds 99.9%. This means that the pregnancy tests will correctly yield a positive result 99.9% of the time when immersed in a sample containing 20 miu/ml or greater of the hormone Human Chorionic Gonadotropin (hcg). The accuracy of most brands of pregnancy tests, generally speaking, tends to be around the 99% mark. These tests are calibrated such that a faint test line will be visible at 20 miu/ml hcg, while no test line should be visible at lower levels.
