Vitamin B7
VIT B7
Description
"Vitamin B7" test evaluates biotin levels in your blood, a key nutrient for hair health, skin repair, and nerve function. Doctors may recommend it when symptoms like thinning hair, brittle nails, or unexplained fatigue appear. Low levels are often linked to poor diet, malabsorption, or prolonged antibiotic use. Results help guide treatment plans including supplements or dietary adjustments. Monitoring biotin supports keratin production, energy metabolism, and overall cellular function over time.

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: 250–329 pmol/L
SI Unit: 250–329 pmol/L
Normal Range
For All Individuals:
Conventional Unit: 133–329 pmol/L
SI Unit: 133–329 pmol/L
Results That Differ From The Norm (Direct and Indirect Causes)
Increased levels may indicate:
Excessive vitamin B7 supplementation
Excessive B7-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 biotin.
Diagnosis of Deficiency: Identifies deficiency to address hair, skin, and neurological issues.
Monitoring Deficiency Treatment: Tracks success of dietary or supplementation interventions.
Evaluation of Malabsorption: Detects absorption issues linked to gastrointestinal conditions.
Hair and Skin Health: Manages hair and skin conditions like brittle nails and thinning hair.
Pediatric Assessment: Ensures adequate biotin levels for growth and development 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.
