However, blood test revealed a raised creatinine level (112 μmol/L; reference range: 65–107 μmol/L), elevated C-reactive protein (CRP, 56 mg/L; reference range: <7 mg/L), anaemia (haemoglobin 7.7 g/dL; reference range: 13–18 g/dL), thrombocytopenia (platelets 96 × 109/L; reference range: 150–400 × 109/L), and hypalbuminaemia (albumin 31 g/L; reference range: 35–50 g/L), which prompted an admission for further evaluation. Here, CRP is linked to anemia.
