Abstract

The invention discloses a red cell G6PD lack disease dual-enzyme ratio check method, a relative agent box and a relative method, belonging to blood check technical field. The invention checks the ascending speeds A and B when G6PD catalyzes G6P and 6GPD catalyzes 6PG of one sample at 340nm absorbance, to directly process judgment based on the ratio between A and B. The agent box is composed of R2/G6P, R2/6PG, and R1 buffer liquids. And the method comprises that first preparing hemolysis liquid of object sample, processing test directly on a dual-channel automatic biochemical machine which can directly calculate out the ratio between A and B. The invention has accurate check, simple and quick operation, low cost, and wide application for checking G6PD lack disease.

Description

technical field [0001] The invention relates to blood detection technology, in particular to a double-enzyme ratio detection method for red blood cell G6PD deficiency, and also relates to a test kit for red blood cell G6PD deficiency and a method for using the kit. Background technique [0002] Patients with erythrocyte glucose-6-phosphate dehydrogenase (G6PD) deficiency is a common genetic disease in my country, and the incidence rate is very high in the provinces south of the Yangtze River (about 3-16%). There are about 100 million patients with G6PD deficiency in my country. The disease is usually asymptomatic, but the patient's red blood cells are easily damaged by certain substances and hemolysis occurs, leading to hemolytic anemia, drug hemolysis, favism, etc. The most serious is neonatal hemolysis, which leads to kernicterus and develops into children. Lifelong mental retardation or death. Because the G6PD gene is located on the X chromosome, males have only one X chro...
