Plasma levels of interleukin 6 (IL-6) and IL-8 from platelet units implicated in TRALI reactions.

Levels of IL-6 and IL-8 (pg/mL) are depicted as a function of storage time and are compared with plasma levels drawn from 10 healthy control donors (C, at left of each panel). * indicates a statistically significant (P < .05) difference compared with levels from the healthy controls. Each measurement represents a sample size of 11 to 34.
