What is therapeutic plasma exchange?
Therapeutic plasma exchange, offered at our Castle Rock clinic, separates plasma from your blood. Your blood cells are returned to you with a replacement fluid. Hospitals use it for certain medical conditions. For longevity, it is still an area of active research. We offer it under physician oversight, and only after a consult and a review of your labs and history.
Before you decide
TPE is well established for a set of specific medical indications. Its use in healthy-aging contexts is still being studied. We will tell you which category your situation falls into.

What is therapeutic plasma exchange?
Therapeutic plasma exchange, or TPE, is a procedure that separates the plasma, the liquid part of your blood, from your blood cells, then returns the blood cells to you with a replacement fluid. It is an established hospital procedure for specific medical conditions. At Castle Rock Regenerative Healthcare it is offered under physician oversight, only where clinically appropriate.
Does therapeutic plasma exchange work for anti-aging or longevity?
Not as an established use. For healthy aging, TPE is investigational, and we say so before anyone books. Researchers are studying it and the results so far are early, while TPE is well established only for a set of specific medical conditions treated in hospitals. What we offer is a physician consult and a review of your labs and history first, under Dr. Scott Faulkner, MD, our Medical Director, board certified in Internal Medicine, with a hospital and intensive care background. If TPE does not fit your plan, you hear that at the consult, along with what your provider would suggest instead.
Is therapeutic plasma exchange safe?
It is a monitored medical procedure with real risks, and we run it like one. Our Medical Director, Dr. Scott Faulkner, MD, is board certified in Internal Medicine and comes from a hospital and intensive care background. Before anything is scheduled you have a physician consult, and your labs and history are reviewed. Your provider explains the risks that apply to you first, and every session is done in our clinic under the supervision the procedure needs.
How much does therapeutic plasma exchange cost in Castle Rock?
Therapeutic plasma exchange at our Castle Rock clinic is quoted as one written price after your physician consult and lab review, before anything is booked. You can ask for a written Good Faith Estimate at any time. We do not bill insurance, and FSA and HSA cards work on qualifying services. Cost questions are welcome at the free 30-minute consult, in person or by phone. How our pricing works
Who is a good candidate for therapeutic plasma exchange?
Often someone already following a broader longevity plan who wants the evidence laid out honestly and accepts that this use is investigational. Not everyone is a candidate, and sometimes the answer is no. That call is made at a physician consult, after a review of your labs and history. Book the free 30-minute consult, in person or by phone, to start.
What is the difference between plasma exchange, plasmapheresis and apheresis?
Apheresis is the umbrella term for any procedure that separates blood into parts and keeps or removes one part. Plasmapheresis removes plasma. Therapeutic plasma exchange removes your plasma and returns your blood cells with a replacement fluid, so the plasma is exchanged rather than simply taken. People often use the terms loosely, so ask your provider which one is being described.
Is plasma exchange the same as donating plasma?
No, therapeutic plasma exchange is not the same as donating plasma. When you donate, some plasma is collected for others to use. In TPE, your plasma is separated out and your blood cells are returned to you with a replacement fluid, under physician oversight, as a medical procedure. It also requires a consult and a review of your labs first.
How long does a plasma exchange session take?
A therapeutic plasma exchange session takes about 2 to 3 hours in our clinic, so plan your day around it. At your consultation, your provider tells you how many sessions, if any, make sense for you. Every session is followed up so your provider can review what changed and adjust the plan.
Does insurance cover therapeutic plasma exchange?
No. We do not bill insurance for therapeutic plasma exchange or anything else, and there are no copays. FSA and HSA cards are accepted on qualifying services; the pricing page has the details.
Where is therapeutic plasma exchange offered?
At our Clinical Headquarters, 4348 Woodlands Blvd, Suite 135, Castle Rock, CO 80104. That is where consultations and provider visits happen. Our recovery services are a short drive away at The Longevity Lab on Maleta Lane. Parker, Castle Pines, Lone Tree and Highlands Ranch are all within about half an hour by car.
How do I get started with therapeutic plasma exchange?
Book the free 30-minute consultation. One of our providers answers your questions about scheduling and cost, and we book your evaluation with Dr. Faulkner or Nathan Lehman, PA-C, from there. The treatment decision is made at that visit, and if therapeutic plasma exchange does not fit, your provider says so and tells you what they would do instead.
Do I need a referral or a diagnosis first?
No referral or diagnosis is needed. This service starts with a provider evaluation, booked through the free 30-minute consult.
