1. Disease-specific proteomic fingerprints were found in SARS patients.
2. The two proteomic features yielding the largest receiver operating characteristic curve area (diagnostic accuracy of >95%) were an N-terminal fragment of complement C3c _-chain (m/z 28119) and an internal fragment of fibrinogen alpha-E chain (m/z 5908).
3. In contrast to previous proteomic studies, we found that serum amyloid A was not useful in the diagnosis of SARS.
4. The potential prognostic features of m/z 7768 and m/z 8865 were found to be platelet factor 4 and beta-thromboglobulin, respectively.
