Quick answer

The vitamin B6 test measures the level of vitamin B6 in the blood, most often as its active form, pyridoxal 5-phosphate. Vitamin B6 is needed for processing amino acids, making neurotransmitters, and producing hemoglobin. It is ordered when deficiency or excess is suspected, such as with certain diets, medications, or neurologic symptoms. A blood sample is used, and a healthcare provider interprets the result.

What this test measures

Vitamin B6 is a group of related compounds that the body converts to pyridoxal 5-phosphate, the active coenzyme. This form takes part in more than a hundred reactions, including the metabolism of amino acids, the synthesis of neurotransmitters such as serotonin, and the formation of hemoglobin. It also helps regulate blood sugar.

The test usually measures pyridoxal 5-phosphate in plasma or serum. Because B6 is water-soluble and not stored in large amounts, blood levels reflect recent intake fairly closely. This makes the test sensitive to supplements, and a high result is often related to recent or ongoing supplementation.

Low B6 can occur with poor intake, malabsorption, kidney disease, and some medications. It may be associated with skin changes, anemia, or tingling in the hands and feet. Very high levels, usually from supplements, can also affect nerves, so testing can be useful in both directions.
