VIT B6

Description

"Vitamin B6" test measures pyridoxine levels to evaluate nervous system health, immune response, and red blood cell production. Deficiency may lead to nerve pain, irritability, or low immunity. It’s often ordered for individuals with chronic illness, poor diet, or suspected malabsorption. Low B6 levels prompt adjustments such as supplementation or dietary guidance. Doctors use the results to address symptoms and prevent complications. Routine testing helps sustain neurotransmitter function, energy metabolism, and neurological stability.

Test Group

Vitamin Group, Complete Nutrient Deficiency Group

Test Group Description

Complete Nutrient Deficiency Group: This comprehensive group includes an expanded panel of tests covering a wide range of vitamins, minerals, and other essential nutrients. Vitamin Group: This collection of tests encompasses a range of key vitamins crucial for physiological functions, aiding in nutritional status evaluation and deficiency detection.

Optimal Range

For All Individuals:

  • Conventional Unit: 30.00–50.00 µg/L

  • SI Unit: 122–204 nmol/L

Normal Range

For All Individuals:

  • Conventional Unit: 5.00–50.00 µg/L

  • SI Unit: 20.4–204 nmol/L

Results That Differ From The Norm (Direct and Indirect Causes)

Increased levels may indicate:


  • Excessive vitamin B6 supplementation

  • Excessive B6-containing food intake


Decreased levels may indicate:


  • Alcoholism

  • Celiac disease (Autoimmune disorder affecting the small intestine)

  • Chronic kidney disease

  • Cirrhosis (Liver scarring)

  • Crohn's disease (Inflammatory bowel disease)

  • Dialysis (Kidney treatment)

  • Gastric bypass

  • Hepatitis (Liver inflammation)

  • Malnutrition

  • Short-bowel syndrome (Malabsorption disorder due to shortened bowel length)

  • Ulcerative colitis (Inflammatory bowel disease)

Key Reasons For Testing

  • Nutritional Assessment: Evaluates dietary sufficiency of pyridoxine.

  • Diagnosis of Deficiency: Identifies deficiency to address anemia, neurological symptoms, and dermatitis.

  • Monitoring Deficiency Treatment: Tracks the success of dietary or supplementation interventions.

  • Evaluation of Malabsorption: Detects absorption issues linked to gastrointestinal disorders or syndromes.

  • Neurological Function: Ensures adequate levels for neurological health, preventing neuropathy and seizures.

  • Pediatric Assessment: Supports growth and development by ensuring sufficient pyridoxine levels in children.

Important Note

Any medical procedure yielding results outside the norm may be directly or indirectly linked to the conditions outlined on this page. Various factors, including genetics, medication and supplement usage, recent illnesses, pregnancy, pre-test eating, smoking, and stress, can impact the test's outcome. Additionally, factors like false positives, false negatives, inaccurate analyses, and others can influence results.


Reference ranges, which help healthcare professionals interpret medical tests, may vary depending on age, gender, and other factors. They may also differ between laboratories due to variations in instruments and methods used. Optimal ranges are designed for preventive purposes, aiming to identify trends and potential risks early, while normal ranges reflect conventional laboratory values indicating no current disease or pathology. Your healthcare practitioner may have specific reasons for testing that deviate from the usual or may interpret results differently based on individual circumstances. Proper interpretation typically involves considering clinical findings and other diagnostic tests. Hence, it is crucial to provide your healthcare professionals with a comprehensive medical history, consult with them for result interpretation, and follow their guidance for potential re-testing or additional diagnostics.
