Can the early symptoms of leukemia be detected through a complete blood count (CBC)?

The early symptoms of leukemia usually cannot be directly detected through a routine blood test alone. 1. Limitations of routine blood tests: Routine blood tests primarily evaluate the quantity and morphology of blood components. Although they may provide clues to leukemia, such as abnormally elevated white blood cell counts, anemia, or reduced platelet counts, these abnormalities can also be indicative of other diseases. 2. Complexity of leukemia: Leukemia is a complex hematologic malignancy. Its early symptoms may include anemia, fever, bleeding, joint pain, and hepatosplenomegaly, none of which are specific to leukemia. 3. Necessity for a definitive diagnosis: If a routine blood test reveals abnormalities, further specialized tests such as bone marrow aspiration and cytogenetic analysis are typically required to confirm a diagnosis of leukemia.
