Vitamin B1, plasma
Item Catalog Number: LC121178
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 not required for this test. Always take your medications as prescribed. Do not take your supplements the morning of the test.
Note: Plasma thiamine levels show only recent intake rather than body stores; therefore whole blood is the preferred specimen for thiamin assessment.
