What Is Plasmapheresis?

GCAM collects plasma using a process called Plasmapheresis. This is a special process that separates the plasma from the blood and collects it in a bottle. The uncollected parts of the blood, including red blood cells and white blood cells, are returned to the donor. This allows the donor to donate up to two times a week because they do not have to replenish the parts of the blood that are returned to them.

Plasmapheresis is a process that filters the blood and removes harmful antibodies. It is a procedure done similarly to dialysis. However, it specifically removes antibodies from the plasma portion of the blood. Donation sessions usually take about 90 minutes. However, it can vary from person to person.

Side Effects

Donors are encouraged to hydrate as plasma is roughly 92 percent water. Donors will lose fluid during the process, and in preparation, people should drink plenty of non-alcoholic fluids on the day of their plasma donation both before and after donating. Donors are also instructed to eat something and not to donate on an empty stomach. Eating a small meal or a snack beforehand will mean donors are less likely to feel dizzy or lightheaded.

Safety Regulations

Rest assure that your plasma donation is performed in a highly controlled, sterile environment by professionally trained medical team members following strict safety guidelines for each donor’s comfort and well-being. GCAM uses sterile, one-time-use materials that are disposed of immediately.

GCAM’s facilities are licensed by the Food and Drug Administration, and our centers are routinely inspected by Federal and State agencies. Plasma donors are allowed under federal regulations to donate plasma as frequently as two times within a seven-day period with at least 48 hours between each donation.


Plasma is the clear liquid portion of blood that exists after both red and white cells are removed. Plasma makes up approximately 55% of blood and is composed of 90% water. Through plasmapheresis, the proteins and antibodies collected are used to treat illnesses such as immune system deficiencies, Rh incompatibility, cardiopulmonary needs, pediatric HIV, burn victims, hepatitis, certain liver conditions, bleeding disorders, and shock/trauma victims.

Patients with chronic illness rely on donors to help keep them alive. In addition to saving lives, donors also aid in the process of developing medicines for our everyday lives. That is why donating plasma is so important. For more information on how to donate, please click the following link
