Fluorescence Polarization Immunoassay (FPIA)
Monitor drug therapy
Random 8.0 - 25.0 mcg/ml;
Peak: 15 - 25 mcg/mL;
Trough: < 8 mcg/mL;
Toxic: > 30 mcg/mL.
STAT requests for this test will be performed on a STAT basis (supervisory staff approval is not required).
Collect blood in an SST tube. Centrifuge, aliquot serum into a plastic vial and refrigerate. For maximum clinical significance, usual sampling times are Peak: 0.5 to 1 hour after the end of a 30 minute I.V. infusion (one hour following I.M. administration) or Trough: immediately before next dose is given. Indicate whether specimen is Peak, Trough, or Random level.
