Vitamin B6 Test

The Vitamin B6 test is a blood test that measures the level of Vitamin B6 in the blood. Vitamin B6, also known as pyridoxine, is crucial for the proper functioning of the nervous system, as well as the metabolism of proteins, fats, and carbohydrates.

A Vitamin B6 test may be ordered by a healthcare provider if there are signs or symptoms of a deficiency or excess of Vitamin B6. Symptoms of a Vitamin B6 deficiency may include fatigue, weakness, irritability, and neurological issues. Symptoms of excess Vitamin B6 may include nerve damage, numbness, and tingling.

The test results can help diagnose and monitor conditions such as anemia, neuropathy, and certain metabolic disorders. It can also help determine if supplementation with Vitamin B6 is necessary.

Before taking the test, it is important to follow any fasting instructions provided by your test provider. The test involves drawing blood from a vein, typically from the arm. The blood sample is then sent to a laboratory for analysis.
