Vitamin B1, Whole Blood

This test measures the amount of Vitamin B1, also called thiamine, stored in your blood cells. It helps show whether your body has enough of this nutrient to properly turn food into energy and support nerve function. This measurement is useful for evaluating symptoms like confusion, weakness, or tingling that may indicate a nutritional deficiency. However, this test only reports the vitamin level and does not diagnose the specific medical condition causing a deficiency.
