Urine Glucose (Dipstick)
This dipstick test checks for glucose (sugar) in your urine. Normally the kidneys reabsorb nearly all glucose back into the blood, so very little reaches the urine.
Glucose usually spills into urine only when blood sugar climbs above the level the kidneys can fully reabsorb. That makes it a helpful, if indirect, window into how your body is handling sugar. While blood tests are the main way to assess glucose, a urine finding can be an early prompt to look closer at metabolic health.
A positive result means glucose is present, which most often reflects elevated blood sugar. Less commonly, it can appear when the kidneys reabsorb glucose at a lower threshold than usual, or during pregnancy, prompting a clinician to check blood glucose.
A negative result means no significant glucose was detected in the urine, the normal and reassuring finding.
Negative is the expected result. Because urine glucose is only an indirect signal, a positive finding is confirmed with blood glucose testing interpreted by your clinician.
