Prevalence of pyruvate kinase deficiency among the Chinese : determination by the quantitative assay.
The prevalence of pyruvate kinase (PK) deficiency among the Chinese population has not been established.
Fung et al. (Arch Dis Child 44:373-376, 1969) and Wu et al. (Am J Hemafol 20:139-144, 1985) indicate 3.4% and 2.1% PK deficiency prevalence rates, respectively, the higher figure based on Beutler's screening test  without confirmatory testing.
Neither figure is consistent with the occurrence of hemolytic anemia from this cause in the experiences of hematologists in Hong Kong.
Using the standard quantitative assay, we measured PK activity in blood samples from 1,100 local Chinese people.
The assay was automated on a centrifugal analyser, and the results were expressed in IU per gram of hemoglobin (IU/g Hb).
