Clinical and Interpretive info

  

An interpretive report will be provided

  
False-negative results can occur with acylcarnitine profiling, especially when the patient is carnitine deficient, is affected with a milder variant of a disorder, or when clinical condition or dietary supplementation causes secondary changes to the profile. Results of acylcarnitine profiling should be interpreted in the context of clinical presentation as well as other laboratory tests, which may include urine organic acid analysis and molecular testing.
