Special Info
Do not collect in a gel separator tube. The aminoglycoside sisomicin cross-reacts with the QMS Gentamicin assay due to its structural similarity. Therefore, the results of this assay cannot be used to accurately quantify gentamicin serum or plasma levels in patients on sisomicin in combination with gentamicin.
Clinical Info
Draw 30 minutes after completion of infusion
