Rationale for blood glucose monitoring The measurement of blood glucose provides information on the effectiveness of blood glucose metabolism and guides interventions to achieve optimal glucose control within the body.
What is the purpose of CBG test?
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 purpose of measuring capillary blood glucose?
Capillary blood tests measure whole blood glucose as opposed to venous samples which measure plasma glucose. It is used for the care of people with diabetes, as a monitoring tool, giving a guide to blood glucose levels, at a specific moment in time.
How do I use CBG monitoring?
How do I measure my blood glucose?
- Wash your hands with soapy water and dry them well.
- Insert the test strip into the glucose meter.
- Insert the lancet into the lancing device.
- Prick the end of a finger (on the side).
- Gently squeeze the end of your finger, if necessary.
- Apply the blood to the test strip.
What is the normal CBG 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.
How does a blood glucose monitor work?
How does a continuous glucose monitor (CGM) work? A CGM works through a tiny sensor inserted under your skin, usually on your belly or arm. The sensor measures your interstitial glucose level, which is the glucose found in the fluid between the cells. The sensor tests glucose every few minutes.
What is the importance of BGL monitoring in the fasting patient?
Checking your blood glucose levels will help you to: Find out immediately if your blood glucose levels are too high (hyperglycaemia) or too low (hypoglycaemia), helping you to make important decisions such as eating before exercise, treating a ‘hypo’ or seeking medical advice if sick.
What is the normal range for CBG?
How is CBG measured?
A blood glucose meter is an electronic device for measuring the blood glucose level. A relatively small drop of blood is placed on a disposable test strip which interfaces with a digital meter. Within several seconds, the level of blood glucose will be shown on the digital display.
How CBG test is done?
The procedure involves pricking your finger and putting the blood on a glucose meter strip. The strip is usually already inserted into the machine. Your results will show on the screen in 10 to 20 seconds.
When should glucose monitoring be done?
Testing is usually recommended before meals and at bedtime if you’re taking multiple daily injections. You may need to test only before breakfast and dinner if you use just an intermediate- or a long-acting insulin.
How do you do glucose monitoring?
How do I check?
- After washing your hands, insert a test strip into your meter.
- Use your lancing device on the side of your fingertip to get a drop of blood.
- Touch and hold the edge of the test strip to the drop of blood and wait for the result.
- Your blood glucose level will appear on the meter’s display.
