Which laboratory test is important for monitoring patients on statins?

• A. Liver function tests (LFTs)
• B. Renal function tests
• C. Complete blood count
• D. Thyroid function tests

Answer: (A)

Monitoring liver function tests (LFTs) is crucial for patients on statins due to the potential hepatotoxic effects of these medications. Statins work by inhibiting the enzyme HMG-CoA reductase, which plays a key role in cholesterol synthesis in the liver. While generally well-tolerated, statins can sometimes cause liver enzyme elevations, indicating liver injury or stress. Regular monitoring of LFTs allows healthcare providers to detect and address any hepatotoxicity early on, ensuring patient safety. The other laboratory tests listed, while important in various clinical contexts, do not specifically address the primary concerns associated with statin therapy. Renal function tests are more relevant for medications known to affect kidney function, complete blood counts are used to monitor for conditions like anemia or infection, and thyroid function tests are important for evaluating thyroid disorders, which are not directly related to the side effects of statins. Thus, LFTs remain the focus for safely managing and optimizing statin treatment.
