Nucleocapsid protein as early diagnostic marker for SARS

Emerg Infect Dis. 2004 Nov;10(11):1947-9. doi: 10.3201/eid1011.040516.

Abstract

Serum samples from 317 patients with patients with severe acute respiratory syndrome (SARS) were tested for the nucleocapsid (N) protein of SARS-associated coronavirus, with sensitivities of 94% and 78% for the first 5 days and 6-10 days after onset, respectively. The specificity was 99.9%. N protein can be used as an early diagnostic maker for SARS.
