Details about Vitamin B6 (Pyridoxine)
What is a Vitamin B6 test?
A Vitamin B6 test measures the level of pyridoxine in your blood. Vitamin B6 is essential for amino acid metabolism, neurotransmitter production, immune function, and red blood cell formation.
It plays a key role in mood regulation, brain function, and energy production.
Why do I need a Vitamin B6 test?
Low Vitamin B6 levels can contribute to fatigue, mood changes, nerve symptoms, and immune weakness.
Reasons for testing include:
• Persistent fatigue
• Low mood or irritability
• Numbness or tingling in hands/feet
• Frequent infections
• PMS symptoms
• Poor concentration
• Digestive or absorption issues
• Restricted diet
Benefits of the test
1. Assesses nerve and brain health
2. Helps explain fatigue and low mood
3. Supports immune system evaluation
4. Important for red blood cell formation
5. Detects hidden nutritional deficiency
6. Linked to neurotransmitter production
7. Useful in digestive or absorption issues
8. Guides precise supplementation
Expanded benefit explanation
Vitamin B6 is crucial for nerve signalling, mood balance, and energy metabolism. Identifying deficiency allows targeted correction of symptoms.

Follow these guidelines for accurate results
Sample Timing
Where possible, attend your blood test between 7am and 12pm. Please wait until any short-term illness or infection has fully resolved before testing. Avoid intense exercise for 24–48 hours beforehand, as this can affect certain markers.
Fasting & Hydration
Fasting is not always required, but some tests may recommend it. If fasting is advised, avoid food for 8–12 hours before your appointment and drink water only. Stay well hydrated, as this helps with sample collection and accuracy.
Medications & Supplements
Continue prescribed medications unless advised otherwise by your clinician. Avoid vitamin, mineral, or biotin supplements for at least 24–48 hours before your test, as these can interfere with results. If you are unsure about any medication or supplement, please let us know before your appointment.
Hormones & Menstrual Cycle
For hormone-related tests, timing within your menstrual cycle may be important. If relevant, follow any specific guidance provided on your test page.
If you have any questions or special circumstances, our team is happy to advise before your appointment.
