Donor HIV‑1/2 plus O Antibody Screen with Reflex to Differentiation
Use
This test is used to screen blood and HCT/P (human cells, tissues, and products) donors for HIV‑1, HIV‑2, and group O antibodies using an assay kit that is FDA approved or cleared for donor testing. Reactive results are reflexed to HIV‑1 and HIV‑2 antibody differentiation, per CDC algorithm for fourth‑generation HIV screening to confirm infection status, with follow‑up HIV‑1 RNA testing if differentiation is negative or indeterminate.
Special Instructions
Donor testing is performed at Quest’s dedicated donor testing facility in Chantilly, Virginia. Quest maintains FDA registration for donor testing and uses FDA‑approved assays without laboratory‑developed test modifications.
Limitations
This screen is intended solely for donor screening and should not be used for general diagnostic purposes. Reflexes may incur additional charges. Differentiation may not resolve infection status in early acute infection, requiring RNA testing. Laboratory modifications to FDA‑approved tests are prohibited for donor use.
