Understanding the test
What does the Random Glucose test measure?
Also called Random Blood Sugar
A random glucose can be useful when symptoms occur at a particular time or a fasting sample is impractical. It captures the concentration at that moment.
When it may be requested
A measurement during symptoms
A clinician may want to know the level at the time symptoms occur.
An incidental elevation
A random value can prompt more targeted fasting or longer-term testing when appropriate.
Before your sample

SpecimenPlasma (NaF)
Your checklist
For random glucose, eat as usual unless your clinician says otherwise. Record what and when you last ate and any symptoms at the time of the sample.
A clinician collects venous blood into the container used for glucose testing. When this is a timed sample, the collection time is recorded alongside the result.

Reading your result
Recent meals, physical activity and illness can influence it. The clinician determines whether a timed test or longer-term measure would answer the underlying question better.
What can affect it
- The interval since food is unknown unless recorded.

Patient questions
Before you book
Why am I asked when I last ate?
The same reading has a different context just after a meal and several hours later. Tell the clinician about symptoms at the time as well.
Can medicines affect a random glucose result?
Yes. Corticosteroids, some diuretics, certain antipsychotics and some immunosuppressants can raise glucose, while insulin and sulfonylureas can lower it, particularly with too little food. Bring your medication list and note the time of your last diabetes dose so the result can be read correctly; your doctor decides whether anything needs changing.
Why is a high random result taken more seriously when I have symptoms?
A laboratory random glucose of 200 mg/dL (11.1 mmol/L) or higher with marked thirst, frequent urination or unexplained weight loss can establish diabetes. Contact a clinician promptly. If you also have trouble breathing or are vomiting and cannot keep fluids down, seek emergency care.
Can my home glucose meter diagnose diabetes?
A finger-prick reading can alert you to a change, but a diagnosis requires a laboratory test. Take the reading, time and any symptoms to your clinician so they can decide which test you need.
