Apheresis Platelets, Leukocytes Reduced
- Platelet counts of > 3.0 x 1011 and minimum pH of > 6.2 in 90% of units tested
They also must meet a specific quality testing requirement for residual white cells:
- < 5.0 x 106 residual WBCs in 95% of units tested
Note that 5 x 106 is the U.S. standard; in other parts of the world, including Europe, the number is < 1.0 x 106.
See the glossary entry on leukocyte reduction for more information on why we remove white cells from blood products.
