What is Plasmapheresis?

Plasmapheresis, also known as therapeutic plasma exchange (TPE), is a therapy that removes and replaces the plasma in your blood. Your plasma is the liquid part of your blood. 

If you have a rare disease and your doctor has recommended that you have plasma therapy, your doctor may recommend plasmaphereis.

During plasmapheresis, a machine will remove your blood through a catheter. Your blood then travels through the catheter and into the machine, where it gets separated into:

  • red blood cells,
  • white blood cells,
  • platelets, and
  • plasma.

The machine will get rid of your own plasma and replace it with a safe fluid called substitute plasma. Then, the substitute plasma and your own blood cells (which include red blood cells, white blood cells, and platelets) will be returned to you through a needle.

We offer plasmapheresis at the Acute Dialysis Unit at University of Utah Hospital. One of our nephrologists (kidney doctors) will monitor you during plasmapheresis.
