IMMUNESPAN LITE WELLNESS SCORE™ — FREE

Discover Your Wellness Score — Free, In 30 Seconds

Two numbers from your last blood test. Thirty seconds. Find out where your immune health stands on a science-backed 1–200 scale.

What is NLR?

The Neutrophil-to-Lymphocyte Ratio is one of the most validated markers in immune wellness science — found on any standard Complete Blood Count (CBC).

  • 1
    Find your CBC results Any lab report from LabCorp, Quest, or your doctor will include this.
  • 2
    Locate Neutrophils % and Lymphocytes % Usually listed under "Differential" on your blood count.
  • 3
    Divide Neutrophils by Lymphocytes Example: 62% Neutrophils ÷ 27% Lymphocytes = NLR 2.3
Typical healthy range: 1.5 – 2.5
Elevated (mild): 2.5 – 3.5
Elevated (significant): > 3.5

The optimal NLR rises slightly with age — a 60-year-old with 2.8 is different from a 40-year-old with 2.8. Our formula accounts for this.

How It Works

From One Number to a Complete Wellness Portrait

The Lite Score is the starting point. Here is where it leads.

🔬

Enter Age + NLR

Your NLR is age-adjusted against our NHANES population reference model. A 50-year-old with NLR 2.8 is different from a 40-year-old with the same number. We account for that — instantly, at no cost.

The Science

We Don't Compare You to "Normal." We Compare You to Optimal.

Peak vitality

Beyond "Normal Range"

Medical labs flag results as "normal" if you're in the bottom 95% of the population — including the sick and sedentary. We calibrate against the top quartile of the 128,000+ person NHANES dataset.

Science lab

TRIIM Trial Calibrated

Our Wellness Age model is calibrated against the Fahy et al. 2019 TRIIM trial — the first peer-reviewed study to demonstrate measurable improvement in epigenetic age markers using standard blood biomarkers.

Wellness archetypes

12 Wellness Archetypes

You are not just "inflamed" — you have a specific wellness pattern. Our K-means model assigns you to one of 12 archetypes (examples: Crimson Fox, Pearl Swan, Amber Tiger), each with a distinct education protocol.
