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 Glucose, plasma testing

• Measures blood sugar to spot diabetes and prediabetes early.
• Flags high or low glucose that may explain fatigue, thirst, or dizziness.
• Guides treatment adjustments for diabetes to prevent organ damage over time.
• Tracks glucose control trends when paired with HbA1c and symptom patterns.
• Protects pregnancy outcomes by identifying gestational diabetes risk.
• Clarifies metabolic health before symptoms of heart or kidney disease appear.
• Best interpreted fasting or timed with meals to understand glucose patterns.

What is Glucose, plasma?

Plasma glucose is the concentration of sugar circulating in the liquid portion of your blood at any given moment. It comes primarily from the carbohydrates you eat, which are broken down in your digestive tract and absorbed into the bloodstream, and from glucose released by your liver between meals.

Your body's preferred fuel source

Glucose serves as the main energy currency for nearly every cell in your body, especially your brain, which relies almost exclusively on it. After you eat, insulin helps shuttle glucose from your blood into cells where it's burned for energy or stored for later use.

A tightly controlled balance

Your body works constantly to keep plasma glucose within a narrow range, balancing food intake, hormone signals, and energy demands. When this regulation falters, glucose levels can drift too high or too low, signaling problems with insulin production, insulin sensitivity, or both. Measuring plasma glucose offers a direct snapshot of how well your metabolic machinery is managing this critical fuel at the time of testing.

Why is Glucose, plasma important?

Plasma glucose measures the concentration of sugar circulating in your bloodstream at any given moment. It reflects how well your body balances energy intake, insulin signaling, and cellular fuel delivery. This biomarker is central to metabolic health, brain function, and long-term risk for diabetes and cardiovascular disease.

Your body runs on tight glucose control

Healthy fasting plasma glucose typically ranges from 70 to 99 mg/dL, with optimal values sitting in the lower half of that range. After meals, glucose rises but should return to baseline within a few hours. This balance depends on insulin from the pancreas, glucose uptake by muscles and fat, and glucose release from the liver.

When glucose drops too low

Values below 70 mg/dL signal hypoglycemia, which starves the brain of its primary fuel. You may feel shaky, sweaty, confused, or irritable. Severe drops can cause seizures or loss of consciousness. This is more common in people taking diabetes medications, but can also occur with prolonged fasting, intense exercise, or hormonal imbalances.

When glucose climbs too high

Elevated fasting glucose, especially above 100 mg/dL, suggests insulin resistance or impaired pancreatic function. Over time, high glucose damages blood vessels, nerves, kidneys, and eyes. You may feel fatigued, thirsty, or urinate frequently. Women with gestational diabetes and individuals with prediabetes face heightened cardiovascular and metabolic risks.

Plasma glucose is a window into your metabolic engine, linking diet, hormones, and organ health into a single, actionable number.

What do my Glucose, plasma results mean?

Low plasma glucose levels

Low values usually reflect insufficient glucose delivery to tissues, most often from prolonged fasting, excessive insulin or insulin-like activity, or impaired counter-regulatory hormone responses. Symptoms emerge when the brain is deprived of its primary fuel and include confusion, shakiness, sweating, and in severe cases loss of consciousness. Recurrent low glucose may signal insulin-producing tumors, adrenal insufficiency, advanced liver disease, or medication effects. In newborns and young children, low glucose can reflect immature metabolic pathways or inborn errors of metabolism.

Optimal plasma glucose levels

Being in range suggests balanced insulin secretion, effective glucose uptake by tissues, and intact hormonal regulation by the pancreas, liver, and adrenal glands. Fasting glucose in healthy adults typically sits in the lower half of the reference range, reflecting efficient insulin sensitivity and stable energy metabolism between meals.

High plasma glucose levels

High values usually reflect insulin resistance, insufficient insulin production, or both, and signal disrupted glucose homeostasis. Persistent elevation defines prediabetes and diabetes and increases risk for vascular damage, neuropathy, kidney disease, and impaired wound healing. Acute stress, infection, corticosteroid use, and hormonal disorders such as hyperthyroidism or Cushing syndrome can also raise glucose temporarily.

Factors that influence plasma glucose interpretation

Results vary with fasting status, time of day, recent illness, and medications including steroids and diuretics. Pregnancy lowers fasting glucose slightly but raises postprandial levels. Hemolyzed samples may yield falsely low readings.
