What this test is

This blood test evaluates the amount of vitamin B6, also called pyridoxine, circulating in your body. It is used to help identify a deficiency or, less commonly, an excess. Mild deficiencies are relatively common and can affect energy, mood, and nerve function.

What it measures

  • Vitamin B6 (pyridoxal 5-phosphate) — Reflects the amount of active vitamin B6 in the blood
  • Pyridoxal 5-phosphate (PLP) — The primary active form of vitamin B6 measured in plasma
  • Pyridoxine — One of the forms of vitamin B6 that can be assessed

What the test involves

The test requires a standard blood draw, usually from a vein in your arm. The sample is then sent to a laboratory for analysis.

Why it is often ordered

A clinician may order this test if you have symptoms that could suggest low vitamin B6, such as tingling in the hands and feet, confusion, or certain types of anemia. It may also be ordered when other conditions or medications are known to affect vitamin B6 levels.

Preparation

Preparation instructions can vary, so follow the specific directions provided by the collection lab. In some cases, you may be asked to fast or to avoid certain supplements before the test.

How results are reported

Results are typically reported as a number that indicates the level of vitamin B6 in your blood. Reference ranges differ from one laboratory to another, so your result should always be interpreted using the range provided by the testing lab.

Before you go

  • Whether fasting is required before the blood draw
