Can you please explain to me what genotyping is??And how it's done? And are there different strains of HIV, and if so, how many? ps-very confused
Response from Dr. Young
Hello and thanks for your post.
HIV genotyping refers to testing that determines the genetic sequence or blueprint (or genotype) of key elements of the HIV chromosome. Typically the genes encoding the targets of HIV treatments are the ones that are examined-- namely HIV reverse transcriptase and protease.
There are indeed many different "strains" of HIV-- fortunately, they share highly similar reverse transcriptases and proteases, so that HIV medications are effective across the different strains.
I hope this helps with the confusion.
Be well, BY
