Quick answer
The vitamin B5 test measures pantothenic acid, a water-soluble vitamin involved in energy metabolism. Pantothenic acid is a component of coenzyme A, which helps the body process carbohydrates, fats, and proteins and build fatty acids, cholesterol, and red blood cells. The test uses a blood sample and is ordered when a deficiency is suspected, though it is rare with a varied diet.
What this test measures
Pantothenic acid, or vitamin B5, is needed to form coenzyme A, a molecule central to many metabolic reactions. Coenzyme A helps break down fats and carbohydrates for energy and takes part in building cholesterol, hormones, and other compounds. It also supports the normal production of red blood cells.
The test typically measures pantothenic acid in whole blood or serum. Because the vitamin is present in a wide range of foods, deficiency is uncommon in well-nourished people. When it occurs, it is usually part of a broader pattern of malnutrition rather than an isolated shortage.
Testing may be considered with poor intake, malabsorption, or symptoms that suggest a nutritional problem. The result is interpreted alongside other nutrient tests and a clinical assessment. A healthcare provider uses the full picture to decide whether any action is needed.
