What is the principle of glucose test?

What is the principle of glucose test?

The enzyme glucose oxidase reacts with glucose, water, and oxygen to form gluconic acid and hydrogen peroxide. The hydrogen peroxide can then be used to oxidize a chromogen or the consumption of oxygen measured to estimate the amount of glucose present.

What is the principle of glucose oxidase method?

Other uses of glucose oxidase include the removal of oxygen from food packaging and removal of D-glucose from egg white to prevent browning. PRINCIPLE: Glucose oxidase catalyses the oxidation of β-D-glucose to D-glucono- δ-lactone with the concurrent release of hydrogen peroxide (1).

What is the presence of glucose in urine?

The presence of glucose in the urine is called glycosuria or glucosuria.

What is the excretion of glucose in urine?

Renal glucosuria is the excretion of glucose in the urine in detectable amounts at normal blood glucose concentrations in the absence of any signs of generalized proximal renal tubular dysfunction due to a reduction in the renal tubular reabsorption of glucose.

What is the clinical significance of glucose?

Glucose is a type of sugar. It is your body’s main source of energy. A hormone called insulin helps move glucose from your bloodstream into your cells. Too much or too little glucose in the blood can be a sign of a serious medical condition.

What is the function of glucose oxidase?

Glucose oxidase enzymes are used to remove small amounts of oxygen from food products or glucose from diabetic drinks. Glucose oxidase is playing an important role in color development, flavor, texture, and increasing the shelf life of food products (Khurshid et al., 2011).

Is glucose in urine normal?

The normal amount of glucose in urine is 0 to 0.8 mmol/L (millimoles per liter). A higher measurement could be a sign of a health problem. Diabetes is the most common cause of elevated glucose levels. Your doctor will perform a simple blood test to confirm the diagnosis.

What is the clinical significance of glucose in urine?

If too much glucose gets into the blood, the extra glucose will be eliminated through your urine. A urine glucose test can be used to help determine if blood glucose levels are too high, which may be a sign of diabetes.
