Glucose

Understanding the marker

Glucose is blood sugar, which the body uses for energy. This test measures its level at the time the sample was taken.

Meals, fasting, illness and medicines can affect glucose. The recorded sampling conditions matter when interpreting it. A laboratory range comparison alone does not diagnose diabetes. New symptoms of high or low blood sugar need medical assessment without waiting for another screening test.

What does high Glucose mean?

A high glucose result means blood sugar was above the reported interval at sampling. Fasting status, symptoms, HbA1c and sometimes a repeat test help determine its meaning. Diagnosis requires the appropriate clinical assessment.

What does low Glucose mean?

A low glucose result is assessed with symptoms, meal timing and any medicines. Its significance depends on how low it is and the circumstances of sampling. Symptoms require timely medical advice.
