The customer reported that 3/4 of the way through a therapeutic plasma exchange (tpe) procedure on a patient with demyelinating disease and multiple sclerosis, they began seeing red tinged plasma going up to the remove bag and in the connector.Per the customer, the plasma was a typical yellow-tinged color at the start of the procedure and the hemolysis was not due to disease state or medication given.The operator had already disabled the rbc detector before contacting terumo bct as they had done this before on other procedures and thought this would resolve the issue.Per physician's order, the procedure was ended, and no medical intervention was necessary.The patient is reported as stable.The patient was an in-patient, so they decided to check the patient's cbc the following day, as already planned, and repeat the procedure the following monday, as already planned.The customer declined to provide the patient identifier.The exchange set was disposed of and is not available for return.
