Which of the following is the best method for monitoring thiamine level in blood?
Correct Answer: Transketolase level in blood
Description: Thiamine deficiency is diagnosed by an increase in erythrocyte transketolase activity observed upon addition of thiamine pyrophosphate. The activation of apo-transketolase (the enzyme protein) in erythrocyte lysate by thiamine diphosphate added in vitro has become the accepted index of thiamine nutritional status.
