Laboratory Findings

The diagnosis of beriberi is assisted by a dietary history suggestive of a low thiamine intake and clinical manifestations. However, objective biochemical tests of thiamine status, particularly measurement of erythrocyte transketolase activity (ETKA) and the thiamine pyrophosphate effect (TPPE), provide a sensitive test for thiamine deficiency.
