A viral load in the 500 range is not a cause for panic but does suggest either some problem with adherence, absorption/metabolism of drugs, or resistance. Resistance tests are not full proof and can miss low level resistance and can be less reliable in the HIV range of 500 copies/ml in some labs. I would review other drugs and foods that you are taking (such as grapefruit or St Johns wort)with your HV doc or pharmaacist, consider taking the daruanvir in BID (600 mg with 100 mg ritonavir) dosing, and perhaps use Truvada instead of Combivir while missing zero doses--then repeat viral load. Most of the time the virus should supppress-if not then adding another drug (etravirine or raltegravir might be considered) would be worth considering. KH
