Correlation of the level of serum biomarker—11,695 with the extent of pneumonia in a SARS patient under clinical follow-up. Longitudinal follow- up of the clinical profile of this patient was illustrated in the top panel. Monitoring of the biomarker—11,695 level and chest X-ray opacity score (an indicator of the extent o pneumonia) was shown in the lower left panel. The lower right panel illustrates the biomarker—11,695 in a gel view measured at different time points.
