Additional Information

​Useful For
  • Detecting fatty acid oxidation disorders and several organic acidurias.
  • Evaluating and monitoring patients with fatty acid oxidation and organic acid disorders.
Clinical Indication​
  • hypoketotic hypoglycemia
  • variable degrees of liver disease and/or failure
  • skeletal myopathy, dilated/hypertrophic cardiomyopathy
  • sudden or unexpected death
Interpretation ​ ​The individual quantitative results are not diagnostic by themselves, and are used in order to provide an overall interpretation of the acylcarnitine profile. Interpretation of results is based on pattern recognition.

Do note that abnormal results are not sufficient to establish a diagnosis of a particular disease. In order to provide confirmation of preliminary diagnosis, independent biochemical and molecular genetic tests are required.
 
If sent after office hours, plasma will be separated and stored in Clinical Laboratory -20°C freezer.
