Explain the significance of blast cells in the peripheral blood.

Answer: Each cell is formed from a precursor cell. Blast cells are found in bone marrow. Blast cells are the precursors of blood cells like neutrophils, monocytes, lymphocytes, and erythrocytes. Usually blast cells are present in blood in low count.

High count of Blast cells shows abnormalities. As they are the precursors so high number of precursors cells shows less formation of blood cells. High count of Blast cells may lead to AML (Acute Myeloid Leukemia). AML patient have to go through CBC (complete blood count) Test to check abnormalities.
