iCare STD test kits are highly accurate when used correctly. The accuracy of medical tests is typically measured in terms of sensitivity (detecting true positives) and specificity (identifying true negatives). iCare STD test kits have demonstrated a sensitivity and specificity of over 99%. It's important to note that this test is most accurate when taken at least three months after potential exposure, as it takes this amount of time for your body to develop enough antibodies for the test to detect.
