Vitamin B6 Blood Test
£82.00
Assess your nervous system, metabolism, and nutritional balance with a private Vitamin B6 blood test at Medical Diagnosis Victoria (MDX Victoria) in London.
This test measures the total circulating concentration of vitamin B6 (pyridoxine) in your bloodstream. Vitamin B6 is an essential cofactor involved in amino acid metabolism, neurotransmitter synthesis, immune regulation, and haemoglobin production. Measuring blood levels is highly valuable for investigating suspected deficiencies or excess intake, particularly in patients presenting with unexplained neurological symptoms, peripheral neuropathy, or haematological concerns.
With a 15-day turnaround, this targeted screening provides the reliable clinical data your doctor needs to evaluate your vitamin status, assess special dietary needs, and guide appropriate treatment.

Diagnostic Focus
What is the Vitamin B6 (Pyridoxine) Blood Test?
Because the body cannot produce Vitamin B6, it must be obtained entirely through diet. This critical vitamin is responsible for protein metabolism, forming the myelin sheath that protects your nerves, and creating the haemoglobin that carries oxygen in your red blood cells. A precise blood test helps clinicians identify whether a deficiency is causing neurological or haematological issues, or if excessive supplementation has pushed your levels into a toxic, nerve-damaging range.
Brain & Nerve Health
Evaluating Pyridoxine is essential for:
- Investigating peripheral neuropathy
- Assessing serotonin and dopamine production
- Evaluating mood disorders and depression
- Monitoring cognitive function
Blood & Immune Function
This test is highly useful because it:
- Investigates unexplained microcytic anaemia
- Supports optimal haemoglobin synthesis
- Evaluates frequent immune system illnesses
- Monitors systemic inflammatory responses
Toxicity & Malabsorption
The laboratory provides critical data to:
- Assess risks of high-dose supplementation
- Monitor severe dietary malabsorption
- Evaluate patients with chronic alcoholism
- Guide targeted nutritional therapy safely
Clinical Uses
Why is Blood Testing for Vitamin B6 Important?
Vitamin B6 occupies a unique and somewhat dangerous position among water-soluble vitamins. While deficiencies can cause severe anaemia and mood dysfunction, an excess (almost exclusively from supplements) is highly neurotoxic, potentially causing irreversible sensory nerve damage. A precise blood test provides the exact clinical clarity needed to navigate this narrow therapeutic window safely.
Evaluating Physical Symptoms
You should consider this test if you are experiencing unexplained symptoms associated with abnormal B6 levels, such as:
- Signs of Deficiency: Scaly rashes (seborrheic dermatitis), cracking at the corners of the mouth, confusion, depression, and weakened immunity.
- Signs of Imbalance (Both Excess & Deficiency): Severe “pins and needles” (peripheral neuropathy), numbness, and a loss of coordination in the arms and legs.
Ongoing Medical & Nutritional Monitoring
Doctors frequently recommend B6 testing to manage complex diagnoses, including:
- Patients taking medications known to deplete B6, such as isoniazid (used for tuberculosis) or penicillamine.
- Individuals with chronic gastrointestinal malabsorption conditions (e.g., Coeliac or Crohn’s disease) or severe alcohol dependence.
- Patients currently taking daily high-dose B-complex or bodybuilding supplements presenting with unexplained nerve pain.
Understanding Vitamin B Toxicity & Deficiency
A quantitative Vitamin B6 blood test provides essential diagnostic clarity on your neurological and haematological health. For further clinical guidance on B vitamins and safe supplementation limits in the UK, you can view the official NHS guide on B Vitamins.

Pathology Reports
How To Read Your Laboratory Results
Your report will detail your total circulating Vitamin B6 levels. A low result indicates a true dietary deficiency or a severe malabsorption issue, which could be the direct cause of treatment-resistant anaemia or mood disturbances. A significantly elevated result (hypervitaminosis B6) strongly indicates toxic over-supplementation. If you are experiencing nerve pain and your levels are high, you must discuss immediate cessation of supplements with a doctor to prevent permanent sensory damage.
Results Timeline: Your specialist nutritional report is typically available within 15 days of your blood draw.
Medical Consultation
Need Help? Private GP Consultations
Vitamin B imbalances require careful clinical management, particularly when nerve damage is suspected. If your test demonstrates abnormal B6 levels, or if you are troubled by persistent neuropathy, confusion, or anaemia, we offer private GP consultations on site. Our clinical team can review your report, arrange complementary B12 or Full Blood Count (FBC) tests, and guide you through safe dietary modifications or neurological referrals.

Frequently Asked Questions
Do I need to fast before a Vitamin B6 test?
No special fasting is strictly required. However, it is highly recommended to avoid taking any B-complex vitamins or standalone Vitamin B6 supplements for at least 24 to 48 hours before your blood draw to ensure an accurate baseline reading.
What are the symptoms of a Vitamin B6 deficiency?
Symptoms can include peripheral neuropathy (tingling or numbness in the hands and feet), microcytic anaemia, a weakened immune system, depression, confusion, and a scaly rash on the skin.
Can taking too much Vitamin B6 be dangerous?
Yes. Unlike many other water-soluble vitamins, excessive long-term supplementation of Vitamin B6 can cause severe, sometimes irreversible nerve damage known as sensory neuropathy, leading to profound numbness and loss of coordination.
Why does this test take 15 days to process?
Accurately measuring total active Vitamin B6 (pyridoxal 5′-phosphate) in the blood requires highly specialised laboratory techniques, such as High-Performance Liquid Chromatography (HPLC), which involves meticulous processing to ensure clinical accuracy.
Is the phlebotomy fee included in the £82.00 price?
No, the £24.00 phlebotomy service fee is separate and covers the professional process of drawing your blood at our Victoria clinic, ensuring clear pricing and no hidden costs.
Online Trends
Most Searched Online Questions About Vitamin B6
Why is Vitamin B6 important for brain health?
Vitamin B6 is essential for the production of vital neurotransmitters, including serotonin, dopamine, and GABA. These chemicals regulate emotions, mood, and sleep, making B6 critical for overall cognitive and psychological well-being.
What foods are naturally high in Vitamin B6?
Rich dietary sources of Vitamin B6 include poultry (chicken and turkey), fish, potatoes, chickpeas, and non-citrus fruits like bananas. A balanced diet easily provides sufficient B6 for most healthy adults.
How does a B6 deficiency cause anaemia?
Vitamin B6 is a required coenzyme in the synthesis of haem, the iron-containing component of haemoglobin. Without enough B6, your body cannot produce healthy red blood cells, leading to microcytic anaemia, which mimics the symptoms of iron deficiency.
