Biochemical Genetics Laboratory Carnitine, Free and Total
INDICATIONS FOR TESTING:
Carnitine analysis of serum is indicated in patients presenting with chronic muscle weakness, hypotonia, cardiomyopathy, lipid storage myopathy, SIDS, failure to thrive, hypoglycemic episodes or metabolic acidosis. Analysis of urine is indicated when a renal transport defect is suspected and after low serum values have been established.
Determination of free and total carnitine is performed by a radioistopic enzymatic procedure. Free carnitine is determined by incubating acetyl-CoA radiolabeled with C14, with carnitine acetyltransferase and measuring the labeled acetylcarnitine produced. Total carnitine is determined in the same manner after the sample has been hydrolyzed in an alkaline medium.
Carnitine analysis is completed within a time of 3 working days following specimen receipt. Samples are batched.
