Which tests are essential to monitor when using thionamides like methimazole or propylthiouracil in thyroid storm management?

Explanation:
When using thionamides in thyroid storm, the main concern is potential adverse effects on blood and liver. Thionamides can cause agranulocytosis, a dangerous drop in neutrophils, and hepatotoxicity. Because of that, checking a complete blood count with differential can detect neutropenia early, and monitoring liver enzymes (typically AST/ALT and bilirubin) helps identify Drug-induced liver injury. These tests are essential to catch serious side effects promptly while the drug is in use. TSH isn’t useful for acute monitoring in thyroid storm since it changes slowly and won’t reflect rapid clinical shifts. Serum calcium and blood glucose aren’t specifically tied to thionamide monitoring, so they aren’t the primary tests needed here.
