Initial blood investigations (Table 1) revealed leukocytosis, with a white cell count (WCC) of 13.4 ×109/L, absolute neutrophil count (ANC) of 11.0 ×109/L, a prolonged aPTT of 78 seconds (reference: 28-40 seconds), a normal prothrombin time (PT), and a normal C-reactive protein (CRP). Here, CRP is linked to Increased total leukocyte count.
