What is the normal capillary blood glucose level?

A blood glucose test is a blood test that screens for diabetes by measuring the level of glucose (sugar) in a person’s blood. Normal blood glucose level (while fasting) range within 70 to 99 mg/dL (3.9 to 5.5 mmol/L). Higher ranges could indicate pre-diabetes or diabetes.

What is the capillary blood glucose?

Abbreviation: CBG. The level of circulating blood glucose as measured by glucometer analysis of a fingerstick sample. Regular measurements of CBG allow diabetic patients to make frequent adjustments in their caloric intake, exercise levels, and use of antidiabetic medications, esp. insulin.

Is glucose higher in capillary or venous blood?

Normal physiology, specifically the rate at which glucose is extracted from blood by tissues, determines that in the postprandial (non-fasting) state, capillary (whole) blood glucose is slightly higher than venous (whole) blood.

What is random capillary blood glucose estimation?

A random glucose test, also known as a random blood glucose test (RBG test) or a casual blood glucose test (CBG test) is a glucose test (test of blood sugar level) on the blood of a non-fasting person. This test assumes a recent meal and therefore has higher reference values than the fasting blood glucose (FBG) test.

What does high capillary blood glucose mean?

What is the purpose of capillary blood glucose?

Capillary blood glucose (CBG) testing was developed to replace home urine glucose testing by patients or by the staff in physician offices. CBG testing can also be applied in the hospital laboratory as a cost-effective method to rapidly test blood glucose levels.

What is the difference between capillary and venous blood glucose?

There are a few differences between fasting capillaries glucose and fasting venous glucose, while postprandial venous blood glucose level is lower than postprandial capillaries blood glucose by 7%, as glucose is absorbed by the tissue cells via diffusion in peripheral capillaries, and some remaining glucose return to …

Why is capillary blood glucose higher than venous?

The glucose concentration in the water that makes up plasma is equal to that of erythrocytes. Plasma has greater water content than erythrocytes and, therefore, exhibits higher glucose levels than whole blood.
