Vitamin B12 LabCorp

Vitamin B12 is important for maintaining a healthy metabolism, energy, and stress. This test is recommended if a patient is anemic (low hemoglobin or hematocrit) in the presence of an elevated MCV (>98). An elevated MCV >98 is a good indication that B12 should be ordered, even without clinical anemia being evident. Low suspected dietary intake (vegan, vegetarian, low red meat intake, no B12 supplementation); gastric bypass patients; patients with surgical procedures performed on the intestines (especially distal ilium); patients seeking enhanced metabolism, energy, weight loss, stress relief, or possible B12 supplementation are also recommended to have this test completed.
