Comments: Carnitine is assayed using carnitine acyl transferase, with and without alkaline hydrolysis of esters. Reported values are total, free, and esterified carnitine.

Sample requirements: Urine, 10-20 mL (minimum 5 mL), frozen without preservatives and shipped frozen (packed with dry ice) and shipped at room temp with original volume specified. Plasma, ³1 mL (0.5 mL) from heparinized blood (green top tube) supernatant from clinical centrifugation (within 20 minutes) promptly frozen and shipped frozen (packed with dry ice) and shipped at room temperature with original volume specified. Tissue, at least 1 gram muscle, rapidly frozen at -70°C, stored and shipped frozen (packed with dry ice).
