Any initially reactive sample is retested twice. Samples reactive in two out of three assays are further confirmed with a more specific test, such as the Western blot. To get results, patients call the Confide Test Result Center and give their identification number from the test kit. Professional, certified counselors who speak both English and Spanish notify callers of the results if they are positive or inconclusive. Local medical referrals are provided if needed and those who test positive are encouraged to seek medical care.
All conversations are anonymous and confidential.
Although negative results are provided by an automated message, everyone has the opportunity to speak to a counselor. The window period, in most cases, lasts approximately 1 month. FDA's approval was based on data showing that each component of the test system, as well as the complete system itself, was safe and effective for its intended use. Clinical studies showed that the Confide Test Card was able to correctly identify negative samples 99.95 percent of the time based on evaluations of over 3,940 samples. The test also correctly identified 100 percent of 150 known positive samples.
