Get tested with Superpower

If you’ve been postponing blood testing for years or feel frustrated by doctor appointments and limited lab panels, you are not alone. Standard healthcare is often reactive, focusing on testing only after symptoms appear or leaving patients in the dark.

Superpower flips that approach. We give you full insight into your body with over 100 biomarkers, personalized action plans, long-term tracking, and answers to your questions, so you can stay ahead of any health issues.

With physician-reviewed results, CLIA-certified labs, and the option for at-home blood draws, Superpower is designed for people who want clarity, convenience, and real accountability—all in one place.

Key benefits of Urinary Glucose testing

• Screens for diabetes by detecting sugar spilling into urine when blood glucose is high.
• Flags uncontrolled blood sugar that may need medication adjustment or lifestyle change.
• Spots rare kidney disorders where glucose leaks despite normal blood sugar levels.
• Guides diabetes management by tracking how well treatment controls glucose over time.
• Clarifies unexplained symptoms like frequent urination, thirst, or unexplained weight loss.
• Protects pregnancy outcomes by identifying gestational diabetes risk early in prenatal care.
• Best interpreted with blood glucose and HbA1c to confirm diabetes and assess control.

What is Urinary Glucose?

Urinary glucose is sugar (specifically, the simple sugar glucose) that appears in your urine. Normally, your kidneys filter glucose out of your blood but then reabsorb nearly all of it back into circulation, so healthy urine contains little to none.

When blood glucose rises above a certain threshold—typically around 180 mg/dL, known as the renal threshold—the kidneys can no longer reclaim it all. The excess spills into the urine. This overflow is called glucosuria.

Your kidneys act as a glucose gatekeeper

The presence of glucose in urine usually signals that blood sugar has exceeded the kidneys' reabsorption capacity. It most commonly reflects uncontrolled diabetes, but can also occur with certain kidney disorders, pregnancy, or rare genetic conditions affecting glucose handling.

A window into blood sugar control

Urinary glucose offers a noninvasive snapshot of recent blood sugar levels. While not as precise as blood tests, it indicates whether glucose regulation has been significantly disrupted.

Why is Urinary Glucose important?

Urinary glucose reveals whether your kidneys are spilling sugar into the urine, a sign that blood glucose has exceeded the kidney's reabsorption threshold or that the kidney's filtering system is impaired. Normally, glucose is completely reabsorbed back into the bloodstream, so healthy urine contains none or only trace amounts. When glucose appears in urine, it signals that something has overwhelmed this tightly controlled process.

When your kidneys let sugar slip through

In most healthy people, urine glucose remains undetectable because the kidneys efficiently reclaim all filtered glucose when blood sugar stays below roughly 180 mg/dL. This optimal state reflects balanced insulin function and intact renal tubular machinery. Persistently negative urine glucose is the expected norm across all ages and both sexes.

What glucose in your urine actually means

When glucose appears in urine, it most commonly indicates that blood sugar has risen high enough to exceed the kidney threshold, a hallmark of uncontrolled or undiagnosed diabetes. You may notice increased thirst, frequent urination, fatigue, and unintended weight loss as your body loses calories through urine. Rarely, glucose appears despite normal blood sugar due to a benign inherited condition called renal glucosuria, where the kidney threshold is unusually low.

The long view on sugar and kidney health

Persistent glucosuria points to chronic hyperglycemia, which over time damages blood vessels in the eyes, kidneys, nerves, and heart. Monitoring urine glucose helps catch diabetes early and assess metabolic control, protecting long-term organ function and quality of life.

What do my Urinary Glucose results mean?

Low or undetectable urinary glucose

Low values usually reflect normal kidney function and stable blood sugar control. In healthy individuals, the kidneys reabsorb nearly all filtered glucose back into the bloodstream, leaving little to none in the urine. This efficient reclamation preserves energy and prevents nutrient loss. Undetectable urinary glucose is the expected finding in most people and does not indicate a problem.

Optimal urinary glucose levels

Being in range suggests that blood glucose remains below the renal threshold, typically around 180 mg/dL, and that the kidney's proximal tubules are functioning properly. Optimal urinary glucose is essentially zero or trace, reflecting tight metabolic control and intact tubular reabsorption. This is consistent with normal insulin signaling and glucose homeostasis.

High urinary glucose

High values usually reflect blood glucose exceeding the kidney's reabsorption capacity, a condition called glucosuria. This is most commonly seen in uncontrolled diabetes mellitus, where persistent hyperglycemia overwhelms the tubular transport system. Less commonly, it may indicate a primary renal tubular defect such as renal glucosuria, a benign inherited condition, or Fanconi syndrome, where multiple nutrients are lost in urine.

Factors that influence urinary glucose

Pregnancy can lower the renal threshold slightly, making trace glucosuria more common even with normal blood sugar. Certain medications, acute illness, and stress can transiently raise blood glucose and cause spillover into urine.

Urinary Glucose & your health

Urinary glucose measures sugar that spills into your urine when blood glucose rises beyond what your kidneys can reabsorb, typically above 180 mg/dL. It's a window into how well your body regulates blood sugar and kidney filtration.

What high urinary glucose may signal

When glucose appears in urine, it usually means blood sugar has exceeded the kidney threshold, most commonly due to diabetes or prediabetes. This reflects your body's struggle to move glucose from blood into cells for energy, often tied to insulin resistance or insufficient insulin production.

Over time, persistent glucose spillage can signal rising cardiovascular risk, nerve damage, and kidney strain. You may notice increased thirst, frequent urination, fatigue, or blurred vision as blood sugar climbs.

Why tracking urinary glucose supports prevention

Catching glucose in urine early offers a chance to address blood sugar control before complications develop. It complements blood glucose testing and helps monitor how diet, activity, and metabolic health interact. Staying aware of this marker empowers you to protect your kidneys, heart, brain, and long-term energy balance.
