What is considered the most definitive diagnostic test for leukemia?
Correct answer
D
Rationale
The correct answer is D: Bone marrow biopsy and aspiration. This is the most definitive diagnostic test for leukemia because it allows for direct examination of the bone marrow to determine the presence of leukemia cells. It provides important information on the type of leukemia, its stage, and prognosis.
A: Chest X-ray is not a diagnostic test for leukemia as it does not directly assess the bone marrow where leukemia originates.
B: Urinalysis is a test for evaluating kidney function and detecting urinary tract infections, not for diagnosing leukemia.
C: Complete blood count (CBC) can indicate abnormal blood cell counts seen in leukemia, but it does not provide a definitive diagnosis of leukemia.
Overall, bone marrow biopsy and aspiration is essential for confirming a diagnosis of leukemia by directly examining the bone marrow.
