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 Neutrophils testing

• Reveals your body's frontline defense against bacterial infections and inflammation.
• Spots immune system stress from infection, autoimmune disease, or medication effects.
• Flags bone marrow problems that may reduce infection-fighting white blood cells.
• Guides antibiotic decisions when fever or infection symptoms appear unexpectedly.
• Tracks chemotherapy or immunosuppressive drug safety by monitoring infection risk.
• Clarifies unexplained fatigue, recurrent infections, or slow wound healing patterns.
• Best interpreted with total white blood cell count and your symptom timeline.

What is Neutrophils?

Neutrophils are the most abundant type of white blood cell in your bloodstream, making up 50 to 70 percent of all circulating immune cells. They are produced in the bone marrow and released into the blood as part of your body's first-line defense system. These cells are short-lived, typically surviving only 6 to 12 hours in circulation before migrating into tissues or dying off.

Your body's rapid-response infection fighters

Neutrophils act as frontline soldiers against bacterial and fungal infections. When tissue is damaged or invaded by pathogens, chemical signals recruit neutrophils to the site within minutes. They engulf and destroy microbes through a process called phagocytosis, and they release antimicrobial chemicals to kill invaders.

A window into inflammation and immune activity

The number of neutrophils in your blood reflects how actively your immune system is responding to infection, injury, or stress. Because they rise quickly during acute illness and normalize as you recover, neutrophil counts serve as a dynamic marker of immune activation and overall inflammatory status in the body.

Why is Neutrophils important?

Neutrophils are your body's first responders to infection and tissue injury, making up the majority of white blood cells and forming the frontline of your immune defense. They surge to sites of bacterial invasion, engulf pathogens, and release antimicrobial chemicals. Their count reflects how well your bone marrow can mobilize protection and whether your immune system is balanced or overwhelmed.

Typical neutrophil counts range from about 1,500 to 7,000 cells per microliter, with optimal values sitting comfortably in the middle. Values toward the lower end of normal are generally fine if stable, but dips below this range signal vulnerability.

When your infection fighters run low

Low neutrophil counts, called neutropenia, leave you exposed to bacterial and fungal infections that healthy immune systems easily contain. You may experience frequent fevers, mouth sores, skin infections, or pneumonia. This can result from bone marrow suppression due to chemotherapy, autoimmune attack, nutritional deficiencies, or certain medications.

When your immune system is on high alert

Elevated neutrophils, or neutrophilia, typically signal active infection, inflammation, physical stress, or tissue damage. You might see this during bacterial pneumonia, appendicitis, heart attack, or even intense exercise. Chronic elevation can accompany smoking, obesity, or inflammatory conditions like rheumatoid arthritis.

The bigger immune picture

Neutrophil levels connect directly to bone marrow health, inflammatory tone, and infection risk across all organ systems. Persistent abnormalities may point to underlying blood disorders, chronic inflammation, or immune dysfunction that affects wound healing, cardiovascular risk, and long-term resilience.

What do my Neutrophils results mean?

Low neutrophil levels

Low values usually reflect reduced production in the bone marrow, increased destruction in circulation, or sequestration in tissues. This can occur with viral infections that suppress marrow activity, autoimmune conditions where the immune system attacks its own neutrophils, nutritional deficiencies like B12 or folate depletion, or certain medications including chemotherapy. The condition is called neutropenia. When neutrophil counts drop significantly, the body loses its primary defense against bacterial and fungal infections, increasing vulnerability to serious illness.

Optimal neutrophil levels

Being in range suggests your bone marrow is producing neutrophils at a healthy rate and your immune system is maintaining balanced surveillance without excessive activation. Neutrophils typically make up the majority of white blood cells in adults, and stable counts within the reference range indicate readiness to respond to infection or tissue injury without chronic inflammation.

High neutrophil levels

High values usually reflect an active immune response to bacterial infection, physical stress, tissue injury, or inflammation. This is called neutrophilia. The bone marrow releases more neutrophils into circulation to fight invaders or repair damage. Chronic elevation can occur with ongoing inflammation, smoking, metabolic syndrome, or certain blood disorders. Pregnancy and corticosteroid use also raise neutrophil counts physiologically.

Factors that influence neutrophil interpretation

Neutrophil counts vary with acute illness, recent exercise, stress, and time of day. Some individuals have benign ethnic neutropenia with chronically lower baseline counts that are normal for them.
