מגבלות השיטה
Amino acids analysis may be normal when the patient is well and metabolically stable. Specimens collected even after a partial recovery may not reveal diagnostic abnormalities that are more readily detectable, under acute conditions. Dietary factors such as medium-chain triglyceride (MCT) –containing formulas, fasting, ketogenic diet, carnitine supplementation, and total parenteral nutrition may influence acylcarnitine profiles. Non fasting samples.
