Vitamin & Mineral Tests — Reference Ranges
These tests measure vitamin and trace-mineral levels in the blood. Interpretation needs care: some levels, such as vitamin B12, can sit in a grey zone where the number alone does not settle whether a deficiency is present.
This page lists all 12 tests in this group with their typical adult ranges in both unit systems. Open any test for plain-language notes on high and low results and how to prepare.

|---|---|---|---|
| Copper | Cu | 70–140 µg/dL | 11–22 µmol/L |
| Folate, Red Blood Cell | — | 140–628 ng/mL | 317–1,422 nmol/L |
| Folate, Serum | — | 2–20 ng/mL | 4.5–45.3 nmol/L |
| Methylmalonic Acid | MMA | 0–0.40 µmol/L | 0–0.40 µmol/L |

Please note: Reference ranges vary between laboratories, and between the methods and instruments they use — the range printed on your own report is the one your result should be compared with. A result outside the range is not by itself a diagnosis, and a result inside it does not rule out illness. These pages are an educational summary, not medical advice: always discuss your results with the clinician who ordered them, who can interpret them in the context of your health and history.
