Fluorescence spot test screening of G6PD deficiency / 中华检验医学杂志

ABSTRACT

Objective To establish the methods for neonatal screening of glucose 6 phosphate dehydrogenase (G6PD) deficiency. Methods G6PD activity was measured by using fluorescence spot test (FST) with the dry blood sample on the filter paper for neonatal screening. G6PD/6PGD rate test of venous blood samples was further performed for confirmation. Results The positive G6PD deficiency rate was 4.2% and its detection rate was 3.7% in FST for neonatal screening. The conformation rate of FST with G6PD/6PGD rate test for G6PD deficiency was 86.8% and 100% particularly in severe deficiency groups. Both sensitivity and specificity were very high in severe deficiency groups. Conclusions FST is used in neonatal screening of G6PD deficiency because of its high accuracy, applicability, and simplicity Morover, it can test lots of dry blood samples on the filter paper. It is very favorable to diagnose and treat G6PD deficiency early in high incidence districts.
