Vitamin and Micronutrient Tests
Vitamin and micronutrient tests are a set of laboratory analyses aimed at evaluating the levels of essential vitamins and minerals in the body. These indicators reflect metabolic status, immune system function, bone, muscle, nervous system health, and other organ functions.
Vitamins and micronutrients tested
- Vitamins: A, D (25-hydroxyvitamin D), E, K, C, B-complex (B1, B2, B3, B5, B6, B9 — folic acid, B12 — cyanocobalamin).
- Minerals and micronutrients: calcium (total and ionized), magnesium, iron (ferritin, serum iron), phosphorus, potassium, sodium, zinc, copper, chlorides.
Why take vitamin and micronutrient tests
- Diagnose hypovitaminosis, avitaminosis, and hypervitaminosis.
- Identify deficiency or excess of micronutrients affecting health and metabolism.
- Monitor absorption of vitamins and minerals during supplementation and medication.
- Assess risk of anemia, osteoporosis, immune disorders, and other diseases.
- Monitor condition during chronic diseases, endocrine disorders, gastrointestinal and kidney diseases.
Preparation for the test
- Blood should be drawn fasting, at least 8 hours after the last meal.
- Avoid vitamin complexes, supplements, and alcohol 1–3 days before testing.
- Avoid physical exertion and stress before blood collection.
- Inform your doctor about medications that may affect results.
Testing methods
Vitamin and micronutrient levels are determined by biochemical blood analysis using modern methods such as enzyme-linked immunosorbent assay (ELISA), mass spectrometry, and atomic absorption spectroscopy.
Result interpretation
Results are interpreted by a physician considering age norms, sex, and clinical presentation. Deviations may indicate deficiency or excess requiring correction:
- Low vitamin D levels are associated with osteoporosis risk and reduced immunity.
- B-complex vitamin deficiency can lead to anemia and neurological disorders.
- Iron and ferritin imbalances indicate iron-deficiency anemia.
- Calcium and magnesium imbalance affects muscle, nerve, and cardiovascular function.
Advantages of comprehensive testing
- Provide a complete picture of the body’s vitamin and mineral status.
- Help timely detect hidden deficiencies and prevent complications.
- Ensure control over the effectiveness of prescribed therapy and supplements.
Vitamin and micronutrient tests are an important tool for health assessment, deficiency detection, and treatment monitoring. Regular testing helps maintain optimal levels of essential substances and prevent related diseases.
