In terms of LAP score, which statement is true for CML?

Explanation:
LAP score measures alkaline phosphatase activity in neutrophils. In chronic myeloid leukemia, neutrophils arise from a malignant clone with impaired maturation and reduced enzyme activity, so the LAP score is typically decreased. This helps distinguish CML from a leukemoid reaction, where neutrophils are highly activated and the LAP score is elevated. Hence the statement that LAP score is typically decreased is true.
