Vitamin B12

This test measures the amount of Vitamin B12 in your blood, a nutrient essential for making red blood cells and keeping your nervous system healthy. It helps show whether low levels are causing symptoms like fatigue, weakness, or tingling in the hands and feet. This measurement assists doctors in ruling out specific types of anemia and nutritional deficiencies. While it detects abnormal levels, this test alone cannot determine the specific reason for a deficiency, such as diet or absorption problems.
