A CBC showed leukocytosis (6.80 × 109/L), eosinophil (0.38 × 109/L), erythrocyte sedimentation rate (26 mm/h), and antinuclear antibody titer (1:100), while other autoimmune antibodies, procalcitonin, CRP, hepatic/renal function profiles, cardiac enzymes, electrolyte levels, coagulation profiles, tumor markers, and routine urinalysis/stool tests were normal.
