Testing Matters
Diagnostic tests are crucial in managing Chronic Myeloid Leukemia (CML). This article highlights the key tests used for diagnosing and monitoring CML.

Essential Blood Tests
Complete blood count (CBC) and differential count are vital in diagnosing CML. These tests measure the levels of different blood cells and can indicate abnormalities. Elevated white blood cell counts often prompt further investigation for CML, making these tests a starting point for diagnosis.
Genetic Testing for the Philadelphia Chromosome
Identifying the Philadelphia chromosome is critical in confirming a CML diagnosis. This involves cytogenetic testing and polymerase chain reaction (PCR) to detect the BCR::ABL1 gene fusion. These tests are not only important for diagnosis but also for monitoring treatment response and disease progression.
Monitoring Disease Progression
Regular monitoring with molecular tests helps assess how well treatment is working. Quantitative PCR tests measure the level of BCR::ABL1 in the blood, guiding treatment adjustments. Early detection of changes in these levels can prevent disease progression and improve outcomes.
FAQs
What is a CBC?
A CBC measures the levels of different blood cells to detect abnormalities.
How is CML diagnosed genetically?
CML is diagnosed by detecting the Philadelphia chromosome with cytogenetic and PCR tests.
Why is regular monitoring important?
Regular monitoring helps assess treatment effectiveness and prevent disease progression.
Vital Insights
Diagnostic tests are key to effective CML management, guiding both diagnosis and treatment.
