Modern medicine has made remarkable progress in treating complex blood and immune-related disorders, and one of the most important breakthroughs in this field is apheresis. Patients often ask, “How long is the apheresis procedure?” because time, comfort, and recovery are all major concerns when undergoing any medical treatment.
Whether someone is donating plasma, receiving therapy for autoimmune conditions, or undergoing advanced cell collection for cancer therapy, the procedure of apheresis is now widely used across the world. At a professional apheresis center , trained medical staff perform this procedure using advanced equipment designed to make it safe, efficient, and patient-friendly.
Where Is Apheresis Performed?
Apheresis is not done in ordinary clinics. It requires specialized medical equipment, trained staff, and sterile environments. That is why it is always performed in a hospital blood bank, transplant unit, or a certified apheresis center .
These facilities are designed to:
- Monitor patients continuously
- Handle blood safely
- Maintain strict hygiene and infection control
- Use FDA-approved or CE-certified machines
Common Locations for Apheresis
Apheresis is usually performed in:
- Large hospitals
- Cancer treatment centers
- Blood donation units
- Immunology and neurology clinics
- Specialized cell therapy centers
If you are undergoing apheresis for medical treatment, you will usually be admitted as an outpatient, meaning you can go home the same day.
What Is Apheresis?
Apheresis is a medical procedure in which blood is removed from the body, a specific component is separated and collected or removed, and the remaining blood is returned to the patient.
The word “apheresis” comes from a Greek term meaning “to take away.” That is exactly what happens doctors selectively remove harmful or needed components from the blood.
This could include:
- Plasma
- Platelets
- White blood cells
- Red blood cells
- Antibodies
- Stem cells
Through apherese, doctors can treat diseases, prepare patients for transplants, or collect cells for advanced therapies like CAR-T treatment.
Types of Apheresis
The length of the procedure depends on the type of apheresis being performed. Each type has a different purpose and duration.
1. Plasma Exchange (Plasmapheresis)
Plasma is removed and replaced with saline or donor plasma.
Used for autoimmune diseases, neurological disorders, and toxin removal.
2. Platelet Apheresis
Only platelets are collected.
Commonly used for blood donation.
3. Leukapheresis
White blood cells are removed.
Used in leukemia and inflammatory diseases.
4. Red Cell Apheresis
Removes or replaces red blood cells.
Used in sickle cell disease.
5. Stem Cell Apheresis
Stem cells are collected for transplantation.
Each type of apherese has a different processing time, but the overall experience is similar for the patient.
How Long Is the Apheresis Procedure?
The duration of apheresis depends on three main factors:
- The type of apheresis
- The patient’s blood volume
- The purpose of the procedure
Here is a general breakdown:
| Type of Apheresis | Average Time |
| Plasma exchange | 2 to 3 hours |
| Platelet donation | 1.5 to 2.5 hours |
| Leukapheresis | 2 to 4 hours |
| Red cell apheresis | 1.5 to 3 hours |
| Stem cell collection | 3 to 5 hours |
At a professional apheresis center, most patients complete their session within 2 to 4 hours.
Some conditions may require multiple sessions of apherese, spread over several days.
Advantages of Apheresis
Apheresis is preferred over many traditional treatments because of its precision and safety.
Key Advantages
- Targeted treatment
Only the harmful or required blood components are removed. - Minimal blood loss
The rest of the blood is returned to the body. - Faster recovery
Compared to full blood removal, patients recover quickly. - Lower side effects
The risk of complications is much lower. - Highly controlled process
At every apheresis center, machines regulate pressure, temperature, and flow automatically.
These advantages make apherese suitable even for patients who are weak or critically ill.
Benefits for Patients
The benefits of apheresis go far beyond just time efficiency.
Health Benefits
- Removes disease-causing antibodies
- Reduces inflammation
- Improves immune response
- Clears toxins from blood
- Supports organ function
Emotional and Practical Benefits
- No major surgery
- Same-day discharge
- No general anesthesia
- Short procedure time
- Can be repeated safely
At a well-equipped apheresis center, patients are monitored by doctors and nurses throughout the entire apherese process.
Step-by-Step: What Happens During Apheresis
Understanding the process helps reduce fear and anxiety.
Step 1: Patient Preparation
- Blood pressure, pulse, and weight are checked
- A small blood sample may be taken
- You are seated or laid comfortably
Step 2: Inserting the Needles
Two small tubes are inserted into veins—usually in both arms.
One tube removes blood, the other returns it.
Step 3: Blood Separation
The blood flows into the apheresis machine.
It spins and separates the blood components.
This is where apherese happens—only the needed part is taken out.
Step 4: Blood Return
The rest of your blood is mixed with saline and returned to your body.
Step 5: Monitoring
Throughout the procedure, staff at the apheresis center monitor:
- Blood pressure
- Oxygen levels
- Heart rate
- Comfort level
Step 6: Completion
After the machine has collected or removed enough blood components, the procedure ends.
The needles are removed and a small bandage is applied.
Does Apheresis Hurt?
Most patients feel only a small needle pinch at the beginning.
During apherese, you may feel:
- Slight cold sensation
- Tingling in lips or fingers
- Mild fatigue
These effects usually disappear quickly. Staff at the apheresis center are trained to manage discomfort immediately.
How Many Sessions Are Needed?
Some patients need only one session.
Others may need multiple rounds of apherese depending on their condition.
For example:
- Autoimmune disorders: 3–6 sessions
- Stem cell collection: 1–3 sessions
- Plasma donation: once every few weeks
Your doctor will decide based on your medical needs.
Safety and Risks
Apheresis is very safe when done at a certified apheresis center.
Possible mild side effects include:
- Low blood pressure
- Lightheadedness
- Temporary calcium imbalance
- Bruising
Serious complications are extremely rare.
Conclusion
So, how long is the apheresis procedure?
In most cases, it lasts between 2 and 4 hours, depending on the type and purpose. Some advanced treatments may take slightly longer, but patients can usually return home the same day.
When performed at a trusted apheresis center , the apheresis process is safe, effective, and life-saving for many conditions. It allows doctors to remove harmful substances from the blood or collect valuable cells for therapy without putting the patient through major surgery.
With modern technology and trained professionals, apheresis continues to transform the way we treat blood, immune, and cancer-related disorders—making healing faster, safer, and more precise.
