Understand panel differences. Call (877) 731-6362 to schedule testing. --- An HIV test what it screens includes detection of HIV-1 and HIV-2 antibodies and the p24 antigen, depending on the panel selected. The test identifies infection status with high accuracy through blood sample analysis at national labs. Panel size affects detection scope and window. Call (877) 731-6362 to arrange your test. OVERVIEW ## What does an HIV test screen for? An HIV test what it screens includes specific markers of HIV infection such as antibodies to HIV-1 and HIV-2 and, in some panels, the p24 antigen. These components indicate whether a person has been exposed to the virus and if the immune system has responded. Testing is performed on blood specimens collected at nationwide lab partners. TEST PANELS ## How does the HIV test panel size affect what it detects? The HIV test what it screens depends on the panel selected. Standard panels screen for HIV-1 and HIV-2 antibodies. More comprehensive panels include antigen testing, which detects HIV infection earlier by identifying the p24 protein. Choosing a larger panel increases the [detection window](https://amhnationwide.com/hair-follicle-drug-test-detection-window/) and accuracy by combining antigen and antibody testing. Smaller panels may only detect antibodies, which develop later after exposure. Antibody-only panel: detects HIV-1 and HIV-2 antibodies, typically positive 3-12 weeks after exposure. Antigen/antibody panel: detects p24 antigen and antibodies, positive as early as 2-4 weeks after exposure. LAB NETWORKS ## Which labs process the HIV test samples? Samples for the HIV test what it screens are routed through five national lab networks: [Quest Diagnostics](https://www.questdiagnostics.com/), [LabCorp](https://www.labcorp.com/), Omega Labs, United States Drug Testing Labs, and ExperTox. This ensures high-quality testing with certified methods. AMH Nationwide provides the lab order and directs the requester to the nearest collection site within these networks. There is no online ordering; all testing arrangements require a phone call. TESTING PROCEDURE ## How is the HIV test sample collected and processed? The HIV test what it screens uses a blood specimen collected at an authorized collection site. The specimen is sent to one of the five national labs for analysis using enzyme immunoassay and confirmatory testing if needed. Every non-negative screen is reviewed by a certified Medical Review Officer to ensure accurate interpretation and reporting. ## Ready to Screen for HIV?

The HIV test what it screens varies in detection window by panel size. Antibody-only tests detect infection approximately 3 to 12 weeks after exposure. Antigen/antibody combination panels can detect HIV as early as 2 to 4 weeks post-exposure. Early detection panels are preferred for recent exposure screening to reduce the window period.
