Extensive blood work revealed leukocytosis (15.3 cells/mm3) with elevated absolute neutrophil count (72.3%), elevated C-reactive protein (CRP) levels (4.7 mg/L), positive antinuclear antibody (ANA), with mild elevation in anti-extractable nuclear antigen (anti-ENA) and ribonucleoprotein antibody (4.3 units/mL). Here, CRP is linked to Increased total leukocyte count.
