About 3-4ml blood was drawn using a sterile syringe, out of which 1ml of the blood sample was inoculated aseptically in to a blood culture bottle, 1ml of blood, was allowed to clot in a sterile bottle to collect serum for the estimation of C-reactive protein and the remaining 2ml of blood was collected in a sterile bottle containing the anticoagulant EDTA (2-2.5 mg/ml) for estimation of Total WBC count, Absolute neutrophil count, Band cell
Laboratory investigations showed haemoglobin 5.7gm./dl; Total leukocyte count 614.8x10 9 /l, Myeloblast 65%, Promyelocytes 10%, Myelocytes 26%, Metamyelocytes 18%, Band cells
4%, Neutrophils 30% and Lymphocytes 7%: ESR 2mm, platelets 709x10 12 /L.
Laboratory tests revealed the following: hemoglobin 11.7 g/dL, white blood cell count 21.16x[10.sup.3]/[micro]L with 85% neutrophils and 7% band cells
, erythrocyte sedimentation rate 100 mm/h, and C-reactive protein level 15 mg/dL (normal<0.8 mg/dL).
His leukocyte count was 2.4 x [10.sup.3] cells/[micro]L with 42% band cells
, creatinine level was 2.5 mg/dL, and lactic acid level was 1.8 mg/dL.
