Children blood test can see leukemia?

Children's blood routine can indicate leukemia to some extent, but it cannot be diagnosed by blood routine alone.

Some abnormalities in blood routine may be clues to leukemia. For example, abnormal increase or decrease of white blood cell count, hemoglobin and thrombocytopenia. However, these abnormalities are not unique to leukemia, and other diseases may also cause similar changes. Blood routine alone cannot definitely diagnose leukemia. It also needs to be combined with clinical symptoms, such as fever, anemia, bleeding, hepatosplenomegaly, etc., because many conditions may affect blood routine results. Leukemia is usually diagnosed by further bone marrow aspirate examination. Bone marrow cell analysis, including cell morphology, immunophenotype, cytogenetics, etc., can accurately determine whether leukemia is and the specific type of leukemia.
