Laboratory test showed elevated C-reactive protein (CRP, 6.83 mg/dL), soluble interleukin-2 receptor (8093 U/mL), ferritin (612.2 ng/mL), and monoclonal gammopathy of IgM (1647 mg/dL) with decreased IgG (970 mg/dL) and IgA (121 mg/dL), as shown in Table 1. This evidence concerns the gene CRP and monoclonal gammopathy.
