why is maraviroc RO different? you would think that the test would detect if the receptor is occupied regardless of what drug us used, but this article explains that is not the case. very technical article but it appears the drug needs to be used as an agent. if the conclusion is correct that the maraviroc RO is unreliable, and the leronlimab RO is accurate, then leronmlmab is the winner here!! in both HIV and longhaulers and the list of other indications...huge!!
