Additional Information
Due to the potential cross-reactivity between some NAT assays and certain lentiviral vector-based CAR-T cell therapies, clinicians should exercise caution when ordering and interpreting HIV testing in patients who have received CAR-T cell therapy. Some lentiviral CAR-T vectors contain a target region of the test, which can lead to false positive HIV-1 results.
