Utility of Random Blood Sugar Test
- Patients suspected to have high blood sugar levels (Hyperglycemia) for example in known or suspected diabetics
- Suspected low blood sugar level. This could be in an individual taking anti-diabetic medications or clinically suspected hypoglycemia
How random blood Sugar is performed
Whole Blood – Finger prick, venipuncture
- Sanitize finger with alcohol soaked swab and air dry
- insert test strip into glucometer and wait for flashing blood drop icon
- Prick finger with lancing device
- Touch tip of test strip downwards on the drop of blood on the finger.
- Read the results displayed on the glucometer screen
The reference range for random blood sugar is 3.9 – 7.8 mmol/l. A reading below 3.9mmol/l is considered hypoglycemia(low blood sugar), and above 7.8mmol/l is hyperglycemia( or high blood sugar)
Note: One episode of hyperglycemia does not equal diabetes! Additional testing is required to make that diagnosis. Refer to this article, for more comprehensive discussion on laboratory diagnosis of diabetes .
Home Monitoring for diabetics
People living with diabetes are encouraged to monitor their blood sugar levels at home. Although routinely fasting and 2-hour after meal is sufficient, random blood sugar may be dome if features of hypoglycemia e.g. extreme weakness, sweating, reduced concentration are present. Having a glucometer at home is an affordable and convenient way to monitor your blood sugar levels.
