About this test
A blood test designed to evaluate vitamin B1, also known as thiamine.
Thiamine helps the body convert food into energy and supports normal nervous system and cellular function. Testing may be useful for people with fatigue, poor nutrition, heavy alcohol use, malabsorption concerns, bariatric surgery history, chronic gastrointestinal issues, or symptoms that raise concern for possible thiamine deficiency. NIH notes that thiamine is important for energy metabolism and cell growth, development, and function. :contentReference[oaicite:1]{index=1}
