What this test is

This test measures carnitine levels, typically in the blood, to check for a deficiency. Carnitine helps transport certain fats into cells so they can be used for energy. A deficiency can interfere with normal muscle function and fat metabolism.

What it measures

  • Total carnitine — reflects the overall amount of carnitine in the sample
  • Free carnitine — reflects the unbound form available for fat transport
  • Acylcarnitine — reflects carnitine bound to fatty acids
  • Acylcarnitine-to-free carnitine ratio — helps indicate how well carnitine is being used

What the test involves

A healthcare professional collects a blood sample, usually from a vein in the arm, using a standard blood draw. In some cases, a urine sample may also be collected depending on the lab's instructions.

Why it is often ordered

A clinician may order this test when a person has unexplained muscle weakness, fatigue, or other symptoms that could relate to how the body processes fats. It can also be used to monitor known metabolic conditions or the effects of certain treatments.

Preparation

Preparation can vary, so follow the collection lab's instructions carefully. This may include fasting for a period before the sample is taken or avoiding certain foods or supplements.

How results are reported

Results are reported as a numerical value for carnitine, often alongside a reference range. Reference ranges differ between laboratories, so results should always be interpreted in the context of the lab that performed the test.

Before you go

  • Whether fasting or other preparation is required before the sample collection
  • What type of sample will be collected, such as blood or urine
  • How and when results will be shared with you or your healthcare provider
