The Vitamin B1 test, also known as Thiamine or Thiamin test, measures the level of Vitamin B1 in the blood. Vitamin B1 is a water-soluble vitamin that plays a crucial role in converting food into energy, maintaining nerve function, and supporting various metabolic processes in the body. The test helps assess the body's Vitamin B1 status and aids in the diagnosis of Vitamin B1 deficiency or other related conditions.

The Vitamin B1 test measures the concentration of thiamine (Vitamin B1) in the blood. Low levels of Vitamin B1 may indicate a deficiency, while high levels are rare but may be seen in certain medical conditions or after supplementation.

Overnight fasting is required for this test.
