Vitamin B1, Whole blood
Vitamin B1 (thiamine) is an essential nutrient as it plays a vital role in carbohydrate, protein and lipid metabolism. Thiamine deficiency can develop after only one month of a thiamine-free diet. Mild thiamine deficiency occurs in pregnant women (increased requirement), in alcoholics, the elderly, and in malabsorption syndromes. Severe thiamine deficiency is a disorder called beriberi.
Whole blood is the preferred specimen for thiamin assessment since plasma thiamine levels show only recent intake rather than body stores.
Fasting is not required for this test. Take all medications as prescribed.
