Carnitine level testing measures the amount of carnitine in your blood. Carnitine is a substance your body uses to turn fat into energy. This test is ordered when a doctor suspects a carnitine deficiency or a disorder that affects how your body uses fatty acids.

What it measures

  • Total carnitine — The combined amount of all forms of carnitine in your blood.
  • Free carnitine — The form that is readily available for your body to use.
  • Acylcarnitine — Carnitine that is attached to fatty acids, helping them move into cells.
  • Carnitine ratio — A calculated comparison of free carnitine to acylcarnitine, which can help identify certain conditions.

Who it is for

This test is usually ordered by a doctor, often a specialist such as a metabolic geneticist or neurologist, when a patient has symptoms like muscle weakness, low blood sugar, or unexplained fatigue.

Preparation

You may need to fast (not eat or drink anything except water) for several hours before the test. Your doctor will give you specific instructions; otherwise, no special preparation is needed.

Results and what they mean

Results are reported as numbers for each form of carnitine, often with a reference range. Your doctor will interpret these numbers along with your symptoms and other tests. This information is not medical advice; only a qualified healthcare professional can diagnose or treat any condition.
