Leukocyte-poor PRP (P-PRP)
Leukocyte-poor PRP excludes most white cells, typically by drawing a narrower fraction above the buffy coat. It carries a lower inflammatory signal and is associated with less post-injection discomfort.

Figure. Producing leukocyte-poor PRP consistently depends far more on rotor geometry and draw technique than on the price of the machine. A flat, horizontal layer is far easier to draw selectively than a diagonal one.
In practice
Producing leukocyte-poor PRP consistently depends far more on the draw technique and the rotor geometry than on the price of the machine. A flat, horizontal layer is easier to draw selectively than a diagonal one.

- Swing-out rotorA swing-out rotor lets tubes rotate to horizontal under load, so the layers stratify flat and perpendicular to the tube.
- Buffy coatThe buffy coat is the thin layer that forms between the red cells and the plasma after centrifugation.
