What is the difference between HIV RNA and HIV DNA? Do you check DNA level? Thank you
| Response from Dr. Young
Hello and thanks for posting.
HIV RNA tests measure the amount of virus that is circulating in the blood; DNA tests look for viral genetic material that is inside of cells.
We only rarely order DNA tests; primarily in people who have very low (or undetectable) HIV RNA levels, where there is a question HIV infection.
