Ultraviolet blood irradiation draws a small fraction of blood, exposes it to ultraviolet light outside the body, then returns it. Historical infection use and modern clinic interest outpace controlled evidence. For longevity-oriented adults it remains experimental—not a validated lifespan therapy—with mainly needle-site issues and short-lived flu-like fatigue. (Full Review)
| Marker | Target | Why |
|---|---|---|
| CBC with differential | Individual baseline; investigate unexplained cytopenias | Infection response and procedural blood-loss tolerance |
| CRP (hs-CRP) | Often <1.0 mg/L in optimization contexts | General inflammation trend |
| CMP (glucose, electrolytes, renal, hepatic enzymes) | Glucose mid-normal fasting; eGFR stable for age; liver enzymes near personal baseline | Safety around sessions; liver context if viral hepatitis history |
| Indication-specific viral load or culture data | Per disease guidelines | Objective infection endpoint when relevant |
| Blood pressure and orthostatic vitals | Individual optimal; no symptomatic drop | Detect hypotension risk |
Cadence: Clinical check each visit; labs at ~4 weeks and course end; every 3–6 months if courses repeat
