Abstracts: Novel corona virus COVID-19 suspected patients including 50 samples were collected from different hospitals in Baghdad, Iraq during 5th to 25th of March / 2020. Complete blood count including monocyte, hemoglobin, red blood cell, leukocyte, lymphocyte and platelets count, and serum C- reactive protein diagnosed in 20 patients which are positive to novel covide-19 in Iraq hospital. The result showed that the monocyte count average was 1.5 103 / UL, hemoglobin (Hb) count vary from 9 to 14 g/dl , the red blood cell average count was 4.83 106 / UL, leukocyte average was 16.00 103 / UL, the lymphocyte was 2.5 %, the platelet (PLT) average count was 512 H 103 / UL and the Creactive protein was 19 mg/L. The results showed that the total number of monocyte, hemoglobin (Hb)and red blood cell were slightly decrease or remained normal, while 90% of patients presented the number of leukocytes were highly increased and the percentage of lymphocytes were reduced, platelets count increased in 80 % and the serum CRP was slightly to high increased, except 10 % of patients slightly increase in leukocyte platelets, moderate change in the percentage of lymphocyte and 20% of serum CRP still normal. Blood parameter and serum C-Reactive protein can be an active evaluation index for infectious patients with novel COVID-19.
