Vitamin and nutritional testing covers lab tests used to assess whether the body is getting and absorbing the vitamins and minerals it needs. These tests measure nutrients such as vitamin B12, vitamin D, folate, iron, calcium, and others, and can help detect deficiencies or imbalances. They may be ordered when a person has fatigue, dietary restrictions, digestive conditions, or symptoms that could relate to a nutritional gap. Results are interpreted together, since nutrients interact and a single value rarely tells the whole story.

• Vitamin B12 Supports red blood cells and nerve function.
• Vitamin D Supports calcium absorption and bone health.
• Folate (folic acid) Important for DNA synthesis and red blood cell production.
• Ferritin Reflects stored iron and helps detect low iron.
• Calcium Supports bone health, muscle, and nerve function.
• Magnesium Involved in muscle and nerve function and energy production.

• People with fatigue or symptoms of a nutritional deficiency
• Individuals with restricted, vegan, or vegetarian diets
• People with digestive conditions that affect absorption
• Those wanting a general nutritional assessment

• Fasting may be requested for some components.
• Tell the collector about vitamin and mineral supplements you take.
• Follow any instructions provided for your specific panel.

Results are compared with reference ranges for each nutrient, but the panel is best interpreted as a whole because nutrients interact. Low values may reflect diet, absorption, or increased needs, while high values often relate to supplements. Discuss results with a healthcare provider, who can identify patterns and recommend any follow-up.
