Biomarker education

Glucose

Also called: Blood sugar, Serum glucose, Plasma glucose

Glucose measures the concentration of sugar in the blood at the time the sample was taken.

What it generally measures

Your report lists glucose from a blood sample — often fasting, random, or as part of a metabolic panel. The timing and preparation instructions matter for comparison.

Common units on reports: mg/dL

Why people track it over time

People track glucose across visits or alongside A1C to notice patterns over time. A single reading is a snapshot, not a complete story.

Changes over time do not by themselves establish a diagnosis. Learn more

Questions you might ask a healthcare professional

  • Confirm whether the sample was fasting and for how long.
  • Ask how this value compares with prior glucose results and with A1C if available.
  • Discuss symptoms or timing questions with your clinician — not with an app alone.
