What is the G-6-PDH assay used for?

What is G-6-PDH?

Glucose-6-phosphate dehydrogenase (G-6-PDH) is a cytosolic enzyme located on the X-chromosome and can be found in every bodily cell.  Glucose-6-phosphate dehydrogenase is involved in the normal processing of carbohydrates.  G-6-PDH plays a critical role in red blood cells (RBC’s), protecting them from damage and premature destruction.  The two main products of G-6-PDH are ribose-5-phosphate which is important for DNA, the chemical cousin of RNA.  The chemical reaction produces NADPH which protects bodily cells from reactive oxygen species.

What is the G-6-PDH assay used for?

Glucose-6-phosphate dehydrogenase (G-6-PDH) deficiency is the most common enzyme deficiency in the pentose phosphate pathway, affecting more than 400 million people globally.  G-6-PDH deficiency is an X-linked recessive disorder mainly affecting red blood cells (RBC’s).

A defect in the G-6-PDH enzyme results in premature haemolysis (break down of RBC’s).  If the bone marrow cannot compensate for the reduction of RBC’s, haemolytic anaemia can occur.  Many individuals that are glucose-6-phosphate dehydrogenase deficient are asymptomatic most of the time, however when they are exposed to certain triggering factors, they can develop acute haemolytic anaemia (AHA), which can be life-threatening, especially in children.  Symptoms associated with G-6-PDH deficiency can include paleness, jaundice, dark urine, fatigue, shortness of breath, a sudden rise in body temperature, lower back pain, splenomegaly (enlarged spleen) and a rapid heart rate.  Other symptoms can include nausea, diarrhoea or abdominal discomfort.  It has been noted that glucose-6-phosphate dehydrogenase deficiency is a significant cause of mild to severe jaundice in new-borns.  For more information on haemolytic anaemia, please click here [external link].  Early and accurate diagnosis of glucose-6-phosphate dehydrogenase deficiency is essential in ensuring the successful management of haemolytic anaemia.

The Randox G-6-PDH assay is used for the quantitative in vitro determination of glucose-6-phosphate dehydrogenase in erythrocytes.  The enzyme activity is determined by measurement of the rate of absorbance change at 340 nm due to the reduction of NADP+.
