What lab should be monitored after initiating denosumab therapy?

Explanation:
Denosumab lowers bone resorption by inhibiting RANKL, which can reduce the amount of calcium released from bone into the bloodstream. Because this can lead to hypocalcemia, closely monitoring serum calcium after starting therapy is essential, especially in patients with vitamin D deficiency or kidney disease. It’s common to check baseline calcium, ensure adequate vitamin D and calcium intake, and recheck calcium levels after the first dose (often within a couple of weeks) to catch and treat any drop early. The other labs listed don’t reflect the drug’s immediate effect and aren’t the primary focus for post-initiation monitoring.
