Answer:
The answer for the initial diagnosis of leukemia is A (CBC, differential, platelet count). After that, other studies are indicated in order to classified the disease.
Explanation:
Leukemia is the cancer of the tissues that form the blood in the body. It is classified as lymphocytic leukemia, which affects the lymphocyte cells that form the immune system, and myeloid leukemia that affects the cells that originate red blood cells, white blood cells and platelets.
A) CBC, differential, platelet count
Measure the number of white blood cells, red blood cells and platelets is one of the first test to be carried out on suspicion of suspicion.
Most leukemia patients have too many immature white blood cells (blasts) in the blood and insufficient red blood cells or platelets.
Although these results may suggest leukemia, the disease is usually not diagnosed until a sample of bone marrow cells is analyzed.
B) Cytochemical stains
Cytochemical stains can be performed on peripheral blood smears and bone marrow smears. Used for differentiation and classification of Leukemias.
C) Immunologic surface markers
Here the cell samples are treated with antibodies that adhere only to certain proteins on them. These tests are used for the classification of leukemic cells according to proteins.
