: The provider you spoke with is correct. Most experts agree that RNA testing usually should not be done to check for infection after any particular exposure, at 4 weeks or any other time. A single antigen-antibody (4th generation) test at 6+ weeks is sufficient for conclusive proof someone didn't catch HIV.
