Objective: To discuss the reliability of SARS-CoV antibody detection for SARS diagnosis.
Methods: Using SARS-CoV ELISA kit to detect relevant antibody in fresh serum of healthy, fever, probable, and suspect cases.
Results: The positive rate is 0%, 40%, and 95% respectively in healthy, probable, and suspect cases.
Conclusions: It is reliable to detect SARS-CoV antibody in late suspect patients, but there will be high false-positive result in ordinary fever cases.
