Are Pregnancy Tests Accurate?
Although most of the pregnancy tests make tall claims of being 9%-99% accurate it is a misleading fact. It is because the HCG level varies from woman to woman in the early stages of pregnancy and accurate result can be determined after a week of the period being due. The manufactures make tall claims because today's products are perceptive than yesterday's products.
Of all test, blood test is considered to be the most accurate, but here again if a woman has been on medication for infertility she could be misguided. Moreover the accuracy of pregnancy tests depends largely on the methodology and technique used in the lab.
Although at home pregnancy test claims 97%-99% accuracy, not following instructions given in the kit will maximize inaccuracy. If tests are tampered and done incorrectly it will obviously give inaccurate results. Excessive intake of fluid could dilute the level of hormone present in the urine, thus leading to inaccuracy too. At home pregnancy test may be accurate only after a week of missed period and not in the initial days.
