Soluble CD40L concentration in the plasma of TRALI patients before and after transfusion. Each line reflects the sCD40L in a pretransfusion typing plasma (left) compared with the sCD40L concentration in a plasma sample drawn when TRALI was clinically recognized (right).16 In 8 of 12 TRALI patients, levels of sCD40L concentrations increased at the time TRALI was diagnosed.
