Overview of the experimental study design. The antibody suspension bead array technology was used to generate protein profiles in both BAL and serum. This study was performed as a directed screening using 94 selected target proteins. Towards these, 96 antibodies were used for profiling of both the discovery and verification set of BAL and serum samples. Based on these results, four proteins were selected for further analysis and additional antibodies targeting these proteins were included. As a second verification, the set of 68 samples were analyzed using sandwich assays for two of the proteins
