There is no specific diagnostic test for AOSD; some common laboratory findings are elevated inflammatory markers, including erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), ferritin, thrombocytosis, above-normal aspartate aminotransferase (AST) and alanine aminotransferase (ALT), and anemia [4]. Here, CRP is linked to thrombocytosis disease.
