This assay measures the concentration of thiamine diphosphate (TDP), the primary active form of vitamin B1. Approximately 90 percent of vitamin B1 present in whole blood is TDP. Thiamine and thiamine monophosphate, which comprise the remaining 10 percent, are not measured.
See Compliance Statement B: www.aruplab.com/CS
Whole blood is the preferred specimen for thiamine assessment. Approximately 80 percent of thiamine present in whole blood is found in red blood cells.
