Vitamin B1 (Thiamine), Whole Blood

Thiamine (Vitamin B1) is essential for cellular function, growth, and converting food into energy. This Whole Blood test directly assesses your body's thiamine status by measuring the biologically active form, thiamine diphosphate, which accurately reflects body stores. Because chronic alcohol use, certain medical conditions, and poor diet can severely impact B1 levels, doctors use this test to diagnose deficiency. Measuring this crucial vitamin is vital for patients experiencing symptoms like unexplained fatigue, neurological issues, or delirium. Get key insight into your nutritional status and metabolic health with this important assessment.
