Stability: Specimen stable 4 weeks ambient, 6 weeks refrigerated, or 6 weeks frozen.
Standard Volume: 2 mL serum or plasma.
Minimum Volume: 0.8 mL serum or plasma.
Transport: Refrigerated.
Rejection Criteria: Use of serum separator tube (SST), (PST), or gels.

Amoidarone 1.0-3.0 ug/mL
Desethylamoidarone Not established
Potential toxic level >3.0 ug/mL

Interpretative Data: The therapeutic range of amiodarone is not presently well established. Toxic effects may begin above 3.0 ug/mL. The concentration of desethylamiodarone, a major metabolite, is also reported, but no therapeutic range is available. At steady-state, the metabolite concentration is similar to the amiodarone concentration. This metabolite may be pharmacologically active, but the extent of activity is not known with certainty.
