Better resistance tests
Aug 20, 2002
Will we ever see resistance tests that can work on someone with an undectable vl to give the individual a better look into the future as far as options,stis etc go?Is there away to test virus in lymphoid tissue etc or is this way off.Thank you
Response from Dr. Young
Right now, we'd still need a detectable viral load in the plasma (blood) to check for resistance. The levels required are getting lower and lower (now at 500 copies for some assays). Currently, save for research assays, there is no way to measure resistance in lymphoid tissues.
The key question is how the resistance in other tissues relates to resistance in blood and that remains a largely unsolved answer.
