resistance testing
Sep 11, 2000

hello doctor

how many types of resistance test are available and are they affordable?

Do these test look at the whole regimen or specific drugs?

Response from Dr. Holodniy

Good questions. The two major types of tests are genotypic (looks at the genetic sequence of HIV) and Phenotypic (looks at the growth of HIV in the presence of drugs). Although they both look at resistance differently, they get at the same relative answer. The look at specific drugs and not combinations of drugs. There does not appear at this point to be one advantage of one kind of technology over the other. Affordability is relative. Genotypic tests are about $300-500/test. Phenotypic tests are about $900-1000/test.
