Biomarkers
5 biomarkers tracked with reference ranges and optimal ranges
| Biomarker | Category | Unit | Reference Range | Optimal Range |
|---|---|---|---|---|
| CD4 Absolute | Immunology | cells/μL | 500.0 – 1500.0 | 700.0 – 1200.0 |
| CD4 Percentage | Immunology | % | 30.0 – 60.0 | 35.0 – 55.0 |
| CD4/CD8 Ratio | Immunology | ratio | 1.0 – 4.0 | 1.5 – 2.5 |
| CD8 Absolute | Immunology | cells/μL | 150.0 – 1000.0 | 250.0 – 800.0 |
| CD8 Percentage | Immunology | % | 10.0 – 40.0 | 15.0 – 35.0 |
Understanding Ranges
Reference range — the clinical "normal" range used by labs. Values outside this range are flagged as low or high.
Optimal range — a narrower band associated with better health outcomes in research. Values within reference but outside optimal are marked "suboptimal".
Always consult a healthcare provider for interpretation of your specific results.
