i have just some question;

about the drug resistans "viruses". how can they tell.

the give the patient drug, they see it doesnt work, so they say that the
virus got drug resistable!

but could it be that the body handles the drug diffrently.so it couldnt
have effect any more or that they body just gave up and doenst fight it
anymore!

because you cannot leaf the human body out of the whole picture!

do they do test in the lab! the have virus put drug with it and see what
it does!

how can you tell if it is due to the virus or something else!

Not necessarily. If they undertake a genotypic or phenotypic analysis
and see certain amino acid changes in the RT, then, yes, you would
conclude resistance.

Of course, what it means to say a drug "doesn't work" is rather vague.
For some, a drug doesn't work because of its side effects.

Fight what?

Of course not.

Yes. That's an adequate, if general, description of a phenotype test.

Through genotypic and/or phenotypic testing.
