Laboratory analysis revealed microcytic normochromic anaemia with a haemoglobin level of 10.7 g/dL, neutrophilic leucocytosis of 15,500/μL, an erythrocyte sedimentation rate (ESR) of 78 mm/h, and a C-reactive protein (CRP) level 5 times the upper limit of normal (ULN). Here, CRP is linked to anemia (phenotype).
