Measuring thiamine levels in patients with behavioral changes, eye signs, gait disturbances, delirium, and encephalopathy; or in patients with questionable nutritional status, especially those who appear at risk and who also are being given insulin for hyperglycemia. Highlights.
The biologically active form of the vitamin, thiamine pyrophosphate (TPP), is best measured in whole blood and is not found in measurable concentration in plasma. Plasma thiamine concentration reflects recent intake rather than body stores; therefore, whole blood is the preferred specimen for thiamine assessment.
Clinical Significance. Vitamin B 1 (Thiamine), Blood, LC/MS/MS - Vitamin B1 is required for branched-chain amino acid and carbohydrate metabolism. Vitamin B1 deficiency is most often due to alcoholism or chronic illness. In the early stage, patients with vitamin B1 deficiency exhibit anorexia, irritability, apathy, and generalized weakness.
Thymine is one of the five bases used to build nucleic acids. It is also known as 5-methyluracil or by the abbreviations T or Thy. Thymine is found in DNA, where it pairs with adenine via two hydrogen bonds. In RNA, thymine is replaced by uracil.

Thymine (T) is a key nucleobase in DNA, forming base pairs with adenine and contributing to the genetic code. Learn about its structure, properties, and biological significance.
Thymine is 5-methyl uracil with similar unsaturated ring. Thymine name sounds like thymus gland, the source of isolation of this molecule was found in 1893 by Albert Neumann and Albrecht Kossel. Most important products of thymine are dTMP, dTDP and dTTP (sugar present is deoxyribose here).
