Exclusions include patients being treated for infective endocarditis, neonates, patients on multiple daily doses and renal patients. For these groups, assays results will be discussed individually. Provided your patient has stable renal function and the level is in the therapeutic range, gentamicin trough levels should be measured before the second dose and re-assayed every 2-3 days. For trough (pre-dose) vancomycin levels, the therapeutic range is 5-15mg/L.
