Double filtration plasmapheresis, a long-used hospital blood-filtering procedure for blood-fat and antibody-driven diseases now offered to healthy adults, removes very large molecules from the blood's liquid part. Its firmest effect is a large but short-lived drop in cholesterol-carrying particles. Claims of slower aging and chemical removal rest on studies without comparison groups or on related procedures. It is costly and short-acting, with little evidence of long-term benefit in healthy people. (Full Review)
| Marker | Target | Why |
|---|---|---|
| Fibrinogen | 200–400 mg/dL | Safety check: low levels stop or space sessions |
| Hemoglobin | 12.0–15.5 g/dL women, 13.5–17.5 g/dL men | Safety check: low values defer sessions |
| Platelets | 150,000–450,000/mm³ | Safety check: low values defer sessions |
| LDL cholesterol | Below 55 mg/dL for very-high cardiovascular risk | Marker DFPP is expected to change |
| Lipoprotein(a) | Below 30 mg/dL | Marker DFPP is expected to change |
| HDL cholesterol | Above 40 mg/dL men, above 50 mg/dL women | Marker DFPP is expected to change |
| IgG | 700–1,600 mg/dL | Safety check: low values defer sessions |
| Ferritin | 24–336 ng/mL men, 11–307 ng/mL women | Safety check: low values prompt repletion |
| Vitamin B12 | 200–900 pg/mL | Safety check: low values prompt repletion |
| hs-CRP | Below 1.0 mg/L, low-risk category | Marker DFPP is expected to change |
| PFAS panel (PFOS, PFOA) | No established target; track change from own baseline | Marker DFPP is expected to change; detects rebound |
| Blood pressure and pulse | Not specified in the ER | Safety check throughout each session |
| Coagulation tests | Not specified in the ER | Baseline safety and reference for change |
| Kidney and liver function | Not specified in the ER | Baseline safety and reference for change |
Cadence: Blood pressure and pulse throughout each session; fibrinogen, hemoglobin and platelets before every session in a series; lipids, Lp(a) and hs-CRP 1 day and 2 weeks after the first session, then before each later course; ferritin, vitamin B12 and IgG every 3 months during repeated courses; pollutant panels 4 weeks after a course
