Among the following methods, the one that is MOST sensitive for glucose estimation is:
Correct Answer: GOD POD method
Description: Enzymatic method of glucose estimation is highly specific, giving 'true glucose' values. The glucose oxidase (GOD) and peroxidase (POD) method is the one most widely used. Glucose oxidase is very specific; it conves glucose to gluconic acid and hydrogen peroxide. Peroxidase conves the H2O2 into H2O and nascent oxygen. The oxygen oxidises a colourless chromogenic substrate (e.g., oho dianisidine) to a coloured one; the colour intensity is directly propoional to concentration of glucose.
