Vancomycin is an antibiotic drug used to treat serious, life-threatening infections by gram-positive bacteria that are resistant to less-toxic agents. The reference range for vancomycin trough levels is 10-20 Âµg/mL (15-20 Âµg/mL for complicated infections). The reference range for vancomycin peak levels is 25-50 Âµg/mL. Next. Vancomycin trough concentrations below 10 Âµg/mL are associated with inadequate therapy and an increased risk of developing bacterial resistance. Vancomycin trough concentrations above the therapeutic range may increase the risk of nephrotoxicity.
Hello. delta-9 carboxy thc is the primary pharmacologically active component of marijuana.It is formed by oxidation of 11 hydroxy delta 9 thc in liver and is detectable in plasma and urine for a much longer time than delta 9THC and is therefore the metabolite tested for finding previous marijuana use.ased on these results it would seem that you son had used marijuana shortly before the test since the THC level is still elevated AND the relatively high level of carboxy THC suggest chronic use. Here is some information on the interpretation of levels and the impairment of driving.
