Wow surprise surprise I was reading about this test and searched in on MedHelp and this is where I landed.
I regret no one ever responded to this post. It is an interesting test though if you are treatment naive and already started treatment I wonder why the test.
I was wondering if this test could help determine resistance for those who start with one PI and for some reason need to stop and attempt to re-treat with the other.
