Vitamin B6 Blood Test

Also Known as

B6, PLP, Pyridoxal-5-Phosphate, Pyridoxine

The Purpose of a Vitamin B6 Test

B6, also known as pyridoxal phosphate, is part of the B complex group of vitamins. These nutrients do everything from safeguarding your heart health to regulating your metabolism. A deficiency in any of the B vitamins, including B6, can lead to a range of health problems such as depression, anemia, and low immunity, and symptoms including nausea, fatigue, and memory loss. B6 is typically consumed in food or supplements. You can be at risk of deficiency if you don’t get enough B6 every day or if you have a condition that prevents absorption, such as alcohol use disorder, autoimmune disorders, or kidney disease. A vitamin b6 test helps you keep tabs on your levels so you can track your health and make any needed changes to your diet or lifestyle.

What Does the B6 Blood Test Measure?

This test tells you how much B6 you have in your body.

Who Should Take a B6 Test?

A B6 blood test is a smart, proactive health tool for people who have medical conditions that interrupt vitamin absorption. A test can also help pinpoint whether symptoms—which can also include rashes, weight loss, and mood shifts—are caused by a vitamin deficiency.

B6 Lab Test Preparation

The blood sample is usually collected in the morning after an overnight fast, preferably before taking any medication. Learn how to prepare for a blood test to get the most accurate results.

Vitamin B6 Lab Test Results

Your B6 levels should be above 5.1 µg/L; results between 3.4 and 5.1 µg/L are considered marginal, and below 3.4 µg/L is deficient. If your levels are lower than desired, you may need to incorporate more B6 in your diet with foods such as:

• Avocado
• Banana
• Legumes
• Meat
• Nuts
• Poultry
• Whole grains
