Fatty Acid Profile, Comprehensive,S

Useful For

This serum test is a comprehensive profile that provides information regarding mitochondrial and peroxisomal fatty acid metabolism, and the patient's nutritional status

 

Monitoring patients undergoing diet therapy for mitochondrial or peroxisomal disorders (possibly inducing essential fatty acid deficiency in response to restricted fat intake)

 

Monitoring treatment of essential fatty acid deficiency

 

Monitoring the response to provocative tests (fasting tests, loading tests)
