A blood glucose test is a blood test that screens for diabetes by measuring the level of glucose (sugar) in a person’s blood.
Why It’s Done?
The blood glucose test may be used to:
- Screen for both high blood glucose (hyperglycemia) and low blood glucose (hypoglycemia)
- Help diagnose diabetes
- Monitor glucose levels in persons with diabetes
Depending on the purpose of testing, glucose may be measured on a fasting basis (collected after an 8- to 10-hour fast), randomly (anytime), post prandial (after a meal), and/or as part of an oral glucose challenge or tolerance test (OGTT / GTT).
What The Normal Range of Blood Glucose Level?
|From 70 to 99 mg/dL (3.9 to 5.5 mmol/L)||Normal fasting glucose|
|From 100 to 125 mg/dL (5.6 to 6.9 mmol/L)||Impaired fasting glucose (pre-diabetes)|
|126 mg/dL (7.0 mmol/L) and above on more than one testing occasion||Diabetes|
