What it measures
- Pantothenic acid (vitamin B5) — The main form of vitamin B5 in the blood.
- Whole blood or serum level — Shows how much B5 is circulating in your body.
- Related B vitamins (optional) — Sometimes checked together to assess overall B-vitamin status.
Who it is for
Doctors may order this test for people with symptoms of deficiency, such as fatigue, numbness, or muscle cramps, especially if they have poor nutrition or malabsorption issues.
Preparation

Results and what they mean
Results are reported as a number that your doctor compares to a reference range. Low levels may suggest deficiency, but only a clinician can interpret the result in your context. This is general information, not medical advice.
