The levels of LDH and CRP in the severe group were higher those in the non-severe group (p < 0.01); the levels of albumin, prealbumin, serum uric acid, and LDH were significantly different between the severe group and the healthy control group (p < 0.01) and the levels of prealbumin, serum uric acid, LDH, and CRP in the severe group were significantly different from those in the other viral pneumonia groups (p < 0.01). This evidence concerns the gene CRP and viral pneumonia.
