- Most patients have viral loads that are suppressible to < 50 copies/mL, but about 25% of patients will occasionally have blips up to 400-500 copies/mL, which do not appear to correlate with lack of viral suppression in most studies; thus, an HIV viral load of =< 400 copies/mL for an occasional "blip" will be allowed, if there is documentation of an HIV viral load < 200 on the same regimen and no significant treatment interruption
