Explanation:
From the symptoms which where observed by the primary health care provider, the child had recurrent fevers, bone pain, and a recent loss of weight. While the physical examination revealed scattered petechiae, lymphadenopathy, and bruising. On further Laboratory diagnosis of the blood film, the full blood count revealed:

--> anemia( lack of red blood cells) and
--> an elevated white blood cell count.
The major importance of full blood count is to evaluate the general health and detect a variety of of disorders. Since the blood picture is not normal, the health care provider should refer the child for BONE MARROW BIOPSY.
