What is Therapeutic Plasma Exchange?
A clinically validated procedure that removes aged plasma and replaces it with fresh albumin solution — clearing the inflammatory compounds, oxidized proteins, and senescent factors that drive aging and disease.
Therapeutic plasma exchange (TPE), also called plasmapheresis or PLEX, is the most direct way to address what accumulates in your blood over time. By removing old plasma and replacing it with 5% albumin — a powerful antioxidant and anti-inflammatory protein — TPE resets the biochemical environment your cells operate in. The result is reduced inflammation, improved cellular signaling, and a measurable shift toward younger biological function.
Why Plasma Matters
Plasma is the liquid portion of your blood, comprising roughly 55% of total blood volume. It carries proteins, hormones, nutrients, antibodies, and waste products. Every cell in your body is influenced by what's circulating in plasma — it is the medium through which your organs communicate, your immune system operates, and your tissues receive the signals that determine how they function.
Over time, plasma becomes a reservoir of everything that has gone wrong. Inflammatory cytokines (IL-6, TNF-α, and others) accumulate. Oxidized LDL builds up. Senescent cells secrete a cocktail of damaging molecules known as the SASP — the senescence-associated secretory phenotype. Autoantibodies, environmental toxins, and misfolded proteins (including amyloid-β and tau-related fragments linked to Alzheimer's disease) all collect in this fluid. The plasma that once nourished your cells increasingly tells them to inflame, degrade, and age.
This is where the dilution hypothesis becomes critical. Research has demonstrated that simply diluting old plasma — replacing it with saline and albumin — rejuvenates tissues, activates stem cells, and reverses markers of aging in multiple organ systems. This insight emerged from parabiosis research and has been validated in subsequent human studies. The implication is striking: much of what we call “aging” may be driven not by what the body lacks, but by what has accumulated in the blood.
And the replacement fluid matters. 5% albumin isn't just a filler. It is the most abundant protein in human plasma, a potent antioxidant that binds and neutralizes toxins, and has well-documented anti-inflammatory properties. Replacing plasma with albumin solution provides active therapeutic benefit — not just dilution, but a biochemical reset.
How TPE Works — Step by Step
A safe, well-established procedure performed by Dr. Green in a comfortable clinical setting with advanced apheresis equipment.
Consultation & Evaluation
Before any procedure, Dr. Green conducts a comprehensive evaluation. This includes medical history review, current medications, lab work (CBC, CMP, coagulation panel, inflammatory markers), and a discussion of goals — whether longevity optimization, cognitive support, autoimmune management, or detoxification. A personalized treatment plan is developed based on your specific needs.
Vascular Access
Two peripheral IV lines are placed, one in each arm — similar to a routine blood draw. The procedure is performed in a comfortable clinical setting at Global Apheresis in Mill Valley, CA.
Plasma Separation & Exchange
Blood flows through an advanced apheresis device that uses centrifugal technology to gently separate plasma from blood cells. The old plasma — containing accumulated inflammatory compounds, toxins, and senescent factors — is removed and discarded. It is replaced in real time with fresh 5% albumin solution.
Return & Recovery
Your blood cells, now suspended in clean albumin solution, are returned to your body through the second IV line. The entire procedure typically takes 2–4 hours. Most patients find it comfortable and well-tolerated — many read, work on their laptops, or rest during the session. There is minimal downtime; most patients resume normal activities the same day.
Follow-Up & Protocol
Treatment protocols are tailored to each patient’s goals. Some applications (such as Alzheimer’s support) follow structured multi-session protocols. Others (longevity optimization) may involve periodic maintenance sessions. Dr. Green monitors your response through follow-up labs and ongoing clinical assessment.
Clinical Applications of Therapeutic Plasma Exchange
TPE is not a single-purpose procedure. Its mechanism — clearing harmful plasma contents and replacing them with protective albumin — has demonstrated clinical relevance across multiple areas of medicine. At Global Apheresis, Dr. Green applies TPE in four primary domains:
Alzheimer’s Disease & Cognitive Decline
TPE removes amyloid-β and inflammatory proteins linked to neurodegeneration. The landmark AMBAR trial (322 patients) demonstrated that plasma exchange with albumin replacement slowed cognitive and functional decline in mild and moderate Alzheimer’s disease — with some mild-stage patients showing improvement from baseline.

Research has shown that diluting old plasma and replacing it with albumin rejuvenates tissues, activates stem cells, and reverses biomarkers of aging across multiple organ systems. TPE is the most direct clinical application of this science.
Learn more →Autoimmune Conditions
TPE removes pathogenic autoantibodies, immune complexes, and inflammatory mediators driving autoimmune disease. It is an established treatment for conditions including myasthenia gravis, Guillain-Barré syndrome, multiple sclerosis, CIDP, and many others — with multiple ASFA Category I and II indications.
Learn more →Detoxification & Environmental Toxins
Modern life exposes us to persistent organic pollutants, heavy metals, and environmental toxins that accumulate in plasma. TPE physically removes these compounds, offering a direct detoxification approach that supplements the body’s natural elimination pathways.

Clears Age-Related Compounds
Removes inflammatory cytokines (IL-6, TNF-α), oxidized lipids, senescent cell secretions, and misfolded proteins that accumulate with age. These compounds impair cellular function and drive the chronic low-grade inflammation known as “inflammaging.”
Resets Cellular Signaling
Aged plasma carries signaling molecules that tell your tissues to behave old. By replacing this environment with clean albumin, TPE restores youthful intercellular communication — organ systems begin functioning as they did at a younger biological age.
Reduces Systemic Inflammation
Albumin is a potent antioxidant and anti-inflammatory protein. The replacement solution actively suppresses inflammatory pathways, not just through dilution but through albumin’s direct biochemical properties.
Activates Stem Cell Populations
Research has demonstrated that removing aged plasma factors and providing a clean signaling environment reawakens dormant stem cells, enhancing the body’s natural regenerative and repair capacity.
Improves Cognitive Function
By clearing neurotoxic proteins (including amyloid-β and inflammatory mediators that cross the blood-brain barrier), TPE has shown cognitive benefits in both Alzheimer’s patients and those seeking cognitive optimization.
Supports Immune Rebalancing
For patients with autoimmune conditions, TPE removes the pathogenic antibodies and immune complexes driving disease activity, allowing the immune system to reset toward healthier function.
What to Expect
Dr. Green will order baseline lab work (CBC, CMP, coagulation studies, and inflammatory markers) and review your medical history. Come to your appointment in comfortable clothes with sleeves that can be rolled up above the elbow. Feel free to bring a laptop, book, or headphones. Plan a light snack for afterward.
The session takes 2–4 hours. You'll be seated in a comfortable reclining chair with two IVs placed, one in each arm. Mild tingling or coolness is normal — this is from the citrate anticoagulant and is easily managed. Most patients describe the experience as no more uncomfortable than giving blood. Many read, work, or rest throughout.
Mild fatigue is common for a few hours. Most patients resume normal activities the same day. Some report feeling noticeably better within 24–48 hours — improved energy, mental clarity, and reduced joint stiffness. Dr. Green follows up with post-procedure labs and clinical assessment.
TPE is one of the most well-established procedures in transfusion medicine, with decades of clinical use across thousands of hospitals worldwide. When performed by a trained specialist, serious complications are rare. Dr. Green has personally performed over 500 TPE procedures.
Frequently Asked Questions
What is the difference between TPE, PLEX, and plasmapheresis?
These terms are used interchangeably. Therapeutic plasma exchange (TPE) is the clinical term. PLEX is the common medical abbreviation. Plasmapheresis technically refers to any procedure that separates plasma from blood, but in practice it’s used synonymously with TPE. At Global Apheresis, we use all three terms to mean the same procedure.
Is TPE FDA-approved?
TPE is an FDA-cleared medical procedure with established indications recognized by the American Society for Apheresis (ASFA). ASFA publishes evidence-based guidelines categorizing TPE indications by strength of evidence — from Category I (first-line treatment) through Category IV. The specific indication determines the category; for example, many autoimmune conditions are Category I, while Alzheimer’s disease is currently Category III (optimum role not established, decision-making should be individualized).
How many sessions will I need?
This depends entirely on your goals and clinical situation. Autoimmune flares may require a focused series of 5–7 sessions. Alzheimer’s protocols (based on the AMBAR trial design) involve structured series over weeks to months. Longevity and optimization patients may do periodic maintenance sessions — for example, quarterly or twice yearly. Dr. Green develops a personalized protocol during your consultation.
Does insurance cover TPE?
Insurance coverage depends on the indication. TPE for established medical conditions (such as myasthenia gravis, TTP, or Guillain-Barré syndrome) is typically covered. TPE for longevity optimization or off-label applications may not be covered by insurance. The Global Apheresis team can discuss costs and options during your discovery call.
What are the risks or side effects?
TPE is considered very safe when performed by a trained specialist. The most common side effects are mild and temporary: tingling or numbness around the lips or fingers (from citrate anticoagulant, easily managed with calcium supplementation), mild fatigue, light-headedness, or coolness during the procedure. Serious complications — including allergic reactions, infection at the IV site, or significant drops in blood pressure — are rare. Dr. Green monitors patients throughout every procedure.
How is TPE different from IV therapy, ozone therapy, or other blood treatments?
TPE is fundamentally different from IV infusions, ozone therapy, or chelation. Those treatments add substances to your blood. TPE removes your entire plasma volume and replaces it — it is a full exchange, not a supplement. This makes it the most comprehensive blood-based intervention available, addressing the full spectrum of accumulated harmful compounds rather than targeting one substance at a time.
Where is the procedure performed?
Dr. Green performs TPE at Global Apheresis, located at 655 Redwood Highway, Suite 370, Mill Valley, CA 94941. The facility is purpose-built for apheresis procedures with advanced equipment and a comfortable patient environment.
