Overview of the Vitamin B6 (Pyridoxine)
The Vitamin B6 (Pyridoxine) blood test assesses Vitamin B6 status, an important nutritional marker involved in amino-acid metabolism, neurotransmitter synthesis and Haemoglobin production.
The test contains 1 biomarker: Vitamin B6 (Pyridoxine).
Vitamin B6 refers to a family of related compounds, with pyridoxal-5'-phosphate being the biologically active coenzyme form.
Vitamin B6 is required for production and metabolism of neurotransmitters, including serotonin, dopamine and GABA.
It also participates in Homocysteine metabolism and red blood-cell function.
Deficiency can occur because of inadequate nutrition, significant malabsorption, alcohol misuse and selected medicines.
Importantly, excessive Vitamin B6 supplementation can itself cause peripheral neuropathy.
This makes Vitamin B6 unusual among water-soluble vitamins: both deficiency and chronic excessive supplementation may produce neurological symptoms.
What Does the Vitamin B6 (Pyridoxine) Test Check?
This test measures 1 biomarker.
Vitamin B6 (Pyridoxine)
Measures Vitamin B6 status to support assessment of nutritional adequacy, deficiency and excessive supplementation.
Who May Benefit From the Vitamin B6 (Pyridoxine) Test?
Testing may be useful in people with neurological symptoms, nutritional risk or substantial Vitamin B6 supplementation.
People with unexplained peripheral neuropathy - Both low and excessively high Vitamin B6 exposure can affect peripheral nerves.
People taking high-dose B6 supplements - Testing can identify unexpectedly high levels.
People with restricted diets - Reduced nutritional intake can increase deficiency risk.
People with malabsorption - Gastrointestinal disease can reduce Vitamin B6 absorption.
People with alcohol-related nutritional risk - Multiple B-vitamin deficiencies can coexist.
People with unexplained anaemia under investigation - Vitamin B6 contributes to Haemoglobin synthesis.
People with a previous abnormal Vitamin B6 result - Repeat testing can assess whether concentrations have normalised.
How to Prepare
Do not take unnecessary high-dose B6 immediately before testing.
If neurological symptoms are developing during substantial supplementation, discuss supplement use with a healthcare professional.
Symptoms and Reasons to Consider the Vitamin B6 (Pyridoxine) Test
Symptoms depend on whether Vitamin B6 is deficient or excessive.
Numbness or tingling in the hands or feet - Peripheral neuropathy can occur with excessive supplementation and occasionally deficiency.
Burning or altered sensation in the feet - Neurological symptoms should prompt review of supplement exposure.
Poor balance with long-term high-dose B6 use - Sensory neuropathy can become clinically significant.
Inflamed or cracked skin around the mouth - Deficiency can contribute to mucocutaneous changes.
Sore tongue - Glossitis can occur with several B-vitamin deficiencies.
Anaemia with broader nutritional deficiency - Vitamin B6 participates in haem synthesis.
Fatigue with significant nutritional risk - Deficiency may coexist with other abnormalities.
Long-term use of high-dose B-complex products - Supplemental B6 intake can be much higher than people realise.
New or progressive neuropathy requires clinical assessment.
If high-dose Vitamin B6 supplements are being taken, the total daily dose from all products combined should be reviewed.

Vitamin B6 requires specialist nutritional analysis rather than routine automated testing.
Your report is released once measurement, analytical quality control and laboratory authorisation are complete.
Specialist referral or specimen issues can occasionally extend this timeframe.
Understanding Your Results
A low Vitamin B6 result can support deficiency when nutritional risk or compatible clinical features are present.
A result within the laboratory range suggests adequate measured Vitamin B6 status.
A high result most commonly reflects supplementation.
Persistently elevated Vitamin B6 is clinically relevant because excessive intake can cause sensory peripheral neuropathy, particularly with prolonged exposure.
The laboratory result should therefore be interpreted with the exact supplement dose and duration of use.
