Clinicopathological analysisChanges seen
Haematology• Anaemia (often mild and non-regenerative)
• Microcytosis
• Lymphopenia
• Neutrophilia (+/- left shift)
Serum biochemistry• Hyperglobulinaemia (often polyclonal gammopathy)
• Hypoalbuminaemia (secondary to acute phase protein response; compensatory for hyperglobulinaemia
• Hyperbilirubinaemia
• Low albumin to globulin ratio
• Increased liver enzyme activities (primarily hepatocellular, especially aspartate transaminase)
