Vitamin B1, Whole blood
Item Catalog Number: LC121186
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.
Fasting is required for this test. Always take your medications as prescribed. Do not take your supplements the morning of the test.
Whole blood is the preferred specimen for thiamin assessment since plasma thiamine levels show only recent intake rather than body stores.
