• CPT Code: 80150
• LOINC: 3321-7
• Specimen Type: SST or RED
• Frequency: Setup: Daily; analytic time 1 day
• Instructions: 0.5mL serum from SST or RED tube. REF in plastic vial. Min 0.3mL. Draw immediately prior to next scheduled dose. Spin down within 2 hrs.
• Text: Useful For: Monitoring adequate clearance of amikacin near the end of a dosing cycle. Caution: Aminoglycosides are excreted primarily by glomerular filtration, thus, the serum half-life will be prolonged and significant accumulation will occur in patients with impaired renal function.
• Methodology: Kinetic Interaction of Microparticles in Solution (KIMS)
