Also known as: carnitine esters, acylcarnitine profile analysis.
What is an acylcarnitine profile?
An acylcarnitine profile is a blood test used to check for the presence of genetic disorders related to fatty acid oxidation and several organic acidurieas. If a patient is at risk of having these disorders or is suspected of having it, the doctor may order the test.
What happens during the procedure?
All that’s required for the test is a basic blood draw, typically from the arm but sometimes from another area of the body. Then the blood sample is taken to a laboratory for testing.
Is any special preparation needed?
Samples should be obtained prior to a scheduled meal or feeding; if clinically possible after an overnight fast. The most reliable results are obtained when the sample is collected during an acute illness, or after overnight fasting, if possible. Normal results however may not rule out some of the metabolic disorders although, it is possible to make the diagnosis when the patient is currently in stable metabolic condition.
Deliberate fast to provoke catabolism is not recommended.
What are the risk factors?
There are slights risks of infection, bleeding, bruising or swelling related to the blood draw.
