Rheumatoid Factor (RF) Positive Plasma

Human whole blood is drawn from donors who are positive for rheumatoid factor. The blood is collected into a sterile blood collection bag containing sodium citrate. The blood is then centrifuged, and the clear plasma portion is removed via extraction. The material undergoes viral testing and the final product is frozen at -70C.

Each unit is between 600 and 880 ml in size.  Please contact our office for available donor units.

Minimum order of a 600 ml unit required.  Please contact our office for smaller sizes and custom aliquots.
