The Nutritional Panel includes a variety of tests that can help you determine if you are getting enough nutrition. This panel can also help rule out adrenal gland disorders and malnutrition. It is commonly ordered by doctors before surgery or for patients who are hospitalized or chronically ill. The Nutritional Panel also includes a CBC, which measures important parameters of the cellular makeup of your blood that can  reveal anemia, signs of infection or other factors that may cause fatigue; a CMP, which analyzes electrolytes, sugar, proteins, and enzymes including sodium, potassium, calcium, glucose and liver/kidney function tests; and an Iron and Total Iron Binding Capacity – which measures the amount of iron in your blood.
