Carnitine levels are disturbed in primary disorders of the carnitine cycle, or secondary disturbances of carnitine metabolism due to other biochemical disorders.

 

While plasma or serum carnitine is reduced in primary carnitine deficiency, urine carnitine may be normal or elevated.

 

Dietary intake (meat, carnitine supplementation) may cause increased carnitine values.

 

Abnormal results are accompanied by detailed interpretation including recommendations for follow-up testing.
