CT angiography revealed periprosthetic infection and elevated inflammatory markers (leukocytosis, CRP). Laboratory tests showed leukocytosis of 16.4 × 109/L (reference: 4.0-9.0 × 109/L), anemia with hemoglobin of 108 g/L (reference: 130-170 g/L), elevated ESR of 60 mm/h (reference: <15 mm/h), and C-reactive protein of 120 mg/L (reference: <5 mg/L). Here, CRP is linked to anemia (phenotype).
