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 CRP / Albumin Ratio (CAR) testing

• Reveals the balance between inflammation and nutritional health in one number.
• Flags hidden systemic inflammation that may drive fatigue or chronic symptoms.
• Guides treatment intensity for infections, autoimmune flares, and inflammatory conditions.
• Tracks recovery after surgery, illness, or injury by showing inflammation trends.
• Identifies malnutrition risk in chronic disease, helping protect muscle and immune function.
• Clarifies unexplained weight loss or weakness by linking inflammation to protein depletion.
• Best interpreted alongside individual CRP and albumin levels plus your clinical picture.

What is CRP / Albumin Ratio (CAR)?

The CRP to albumin ratio is a calculated marker that combines two proteins with opposite roles in inflammation and health. C-reactive protein (CRP) is an acute-phase protein made by the liver that rises sharply during inflammation, infection, or tissue injury. Albumin is the most abundant protein in blood, also produced by the liver, and serves as a marker of nutritional status and overall protein synthesis.

Two proteins, one story about balance

By dividing CRP by albumin, this ratio captures the balance between inflammatory stress and the body's baseline protein reserves. A rising ratio suggests inflammation is outpacing the body's ability to maintain healthy protein levels.

Why the ratio matters more than either alone

The CAR amplifies the signal of systemic inflammation while accounting for nutritional and liver function. It reflects how well the body is coping with inflammatory challenges.

A window into resilience and recovery

This ratio has emerged as a tool to assess disease severity, predict outcomes, and monitor recovery in conditions ranging from infections to cancer. It tells a story of biological resilience under stress.

Why is CRP / Albumin Ratio (CAR) important?

The CRP to albumin ratio captures two opposing forces in your body: inflammation rising and nutritional reserve falling. CRP climbs when tissues are injured or infected, while albumin drops when the liver shifts resources toward acute defense or when chronic illness drains protein stores. Together, they reveal how hard your system is working to contain damage and whether it has the metabolic fuel to sustain recovery.

When the ratio stays low, resilience is high

Values near zero suggest minimal inflammation and robust liver function. Your immune system is quiet, protein synthesis is strong, and metabolic reserves remain intact. This pattern supports wound healing, stable blood pressure, and efficient nutrient transport across all organ systems.

A rising ratio signals stress outpacing recovery

As the ratio climbs, inflammation overwhelms the body's ability to maintain protein balance. You may notice fatigue, poor wound healing, or fluid retention as albumin falls and vascular integrity weakens. Chronic elevation appears in sepsis, advanced cancer, heart failure, and severe malnutrition, where the liver cannot keep pace with tissue breakdown.

The ratio predicts outcomes across disease states

CAR integrates immune activation with metabolic capacity, making it a powerful gauge of frailty and prognosis. Higher ratios forecast longer hospital stays, postoperative complications, and mortality in critical illness. Monitoring the trend helps clinicians assess whether interventions are restoring balance or whether the body remains locked in a catabolic, inflammatory spiral.

What do my CRP / Albumin Ratio (CAR) results mean?

Low values of CRP / Albumin Ratio

Low values usually reflect minimal inflammation and well-preserved liver synthetic function. This combination suggests that acute-phase protein production is balanced, with little systemic inflammatory drive and adequate albumin synthesis. It is generally a favorable metabolic state, though extremely low CRP in isolation may occasionally occur in immunosuppressed individuals.

Optimal values of CRP / Albumin Ratio

Being in range suggests a healthy balance between inflammatory signaling and nutritional or hepatic protein status. The ratio integrates two opposing acute-phase proteins: CRP rises with inflammation, while albumin often falls. Optimal values typically sit at the lower end of the reference range, reflecting low-grade inflammation and stable albumin production.

High values of CRP / Albumin Ratio

High values usually reflect active systemic inflammation, hypoalbuminemia, or both. Elevated CRP signals an acute-phase response driven by infection, tissue injury, or chronic inflammatory conditions. Low albumin may indicate poor nutritional intake, liver dysfunction, or increased vascular leak during critical illness. The ratio is used in oncology and critical care as a prognostic marker, correlating with disease severity and outcomes.

Notes on CRP / Albumin Ratio interpretation

The ratio is influenced by acute illness, malnutrition, liver disease, and chronic inflammatory states. It is not standardized across all laboratories, and interpretation depends on clinical context. Pregnancy, recent surgery, and certain medications can alter both CRP and albumin independently.
