Here’s a list of blood tests used to diagnose nutritional disorders, along with their purpose and the key parameters they measure:
1. Complete Blood Count (CBC)
- Purpose: Assesses overall health and detects disorders like anemia, infections, and many other conditions related to nutritional deficiencies.
- Parameters: Hemoglobin, Hematocrit, Red Blood Cells (RBC), White Blood Cells (WBC), Platelets
2. Iron Profile
- Purpose: Diagnoses iron deficiency or overload, common in nutritional disorders like anemia or hemochromatosis.
- Parameters: Serum Iron, Ferritin, Total Iron Binding Capacity (TIBC), Transferrin Saturation
3. Vitamin D Test (25-Hydroxy Vitamin D)
- Purpose: Measures vitamin D levels, essential for bone health and calcium regulation.
- Parameters: 25-Hydroxy Vitamin D (25(OH)D)
4. Vitamin B12 Test
- Purpose: Detects vitamin B12 deficiency, which can lead to anemia and neurological issues.
- Parameters: Serum Vitamin B12 levels
5. Folate (Vitamin B9) Test
- Purpose: Identifies folate deficiency, critical for cell division and DNA production.
- Parameters: Serum Folate levels
6. Calcium Test
- Purpose: Checks calcium levels, important for bone health, muscle function, and nerve signaling.
- Parameters: Serum Calcium levels
7. Magnesium Test
- Purpose: Measures magnesium levels, which are vital for muscle and nerve function, and bone health.
- Parameters: Serum Magnesium levels
8. Zinc Test
- Purpose: Evaluates zinc levels, crucial for immune function, cell growth, and wound healing.
- Parameters: Serum Zinc levels
9. Lipid Profile
- Purpose: Assesses fat metabolism and identifies risks for cardiovascular diseases due to dietary imbalances.
- Parameters: Total Cholesterol, HDL (High-Density Lipoprotein), LDL (Low-Density Lipoprotein), Triglycerides
10. Electrolyte Panel
- Purpose: Detects imbalances in essential electrolytes that may result from poor nutrition.
- Parameters: Sodium, Potassium, Chloride, Bicarbonate
11. Prealbumin Test
- Purpose: Evaluates nutritional status, especially in cases of protein-energy malnutrition.
- Parameters: Serum Prealbumin levels
12. C-Reactive Protein (CRP)
- Purpose: Assesses inflammation which can be influenced by poor nutrition and deficiencies.
- Parameters: Serum CRP levels
These tests help in identifying specific nutrient deficiencies and overall nutritional health, guiding proper dietary and medical interventions.
