Overview
| Vitamin | Name | Main Function |
| B2 | Riboflavin | Energy metabolism, redox reactions, antioxidant defense |
| B3 | Niacin (nicotinic acid) | NAD/NADP cofactor in energy metabolism, DNA repair |
| B12 | Cobalamin | DNA synthesis, red blood cell formation, neurologic function |
Risk Assessment
Test indicated in patients with:
- Unexplained fatigue or anemia
- Neurologic symptoms (e.g., paresthesia, memory issues, ataxia)
- Glossitis, stomatitis, cheilitis
- Dermatitis, pellagra-like symptoms (for B3)
- Malabsorption syndromes (e.g., celiac, IBD, gastric bypass)
- Chronic alcoholism
- Vegetarian or vegan diet (for B12)
- Prolonged use of certain drugs (e.g., metformin, isoniazid, PPIs)
| Vitamin | Normal Range |
| B2 | 1–19 µg/L (plasma riboflavin level) |
| B3 | 0.5–8.45 µg/mL (plasma niacin level) |
| B12 | 200–900 pg/mL (or 150–670 pmol/L) |
Levels between 200–300 pg/mL are often borderline – check methylmalonic acid (MMA) or homocysteine if unsure.
Interpretation of Results
| Vitamin | Deficiency Signs | Excess/Toxicity |
| B2 | Cracks at mouth corners, sore throat, red tongue, eye fatigue |
Very rare |
| B3 | Pellagra (diarrhea, dermatitis, dementia) |
Flushing, hepatotoxicity (with supplements) |
| B12 | Megaloblastic anemia, neuropathy, memory loss, glossitis |
Usually benign unless very high in supplements |
Sample Type
| Vitamin | Sample | Collection Notes |
| B2 | Serum or plasma | Protect from light (photosensitive); fasting preferred |
| B3 | Serum or plasma | Fasting morning sample preferred |
| B12 | Serum | Fasting not essential but may help with standardization |
