There are two main ways of HIV result notification: the first way, some patients go directly to the CDC for HIV preliminary screening, for patients with positive results, the CDC will notify the patients to go directly to the CDC for blood sampling to improve the HIV confirmatory test, the confirmatory test results back to show positive, and then the CDC will notify the patients to go to the CDC to get the confirmatory report for further antiviral treatment. In the second way, some patients go to the hospital for preliminary HIV screening, and when the test result is positive, the hospital will notify the patient to go back to the hospital for HIV confirmatory test, and the hospital will send the blood specimen to the local CDC to complete the HIV confirmatory test, and when the confirmatory test result is returned to the hospital, the hospital will notify the patient to go to the local CDC to get the confirmatory report for further antiviral treatment. The hospital will then notify the patient to go to the local CDC to get the confirmation report and proceed with further antiviral treatment.
