preoperative-lab-checklist

Determines required preoperative labs based on planned procedure, patient conditions, and ASA classification, then checks existing results and generates orders for missing labs. Use when user asks to "check pre-op labs", "preoperative workup", "surgery lab clearance", "pre-surgical labs", "OR readiness", "clearance labs", or needs to verify lab requirements before a scheduled procedure. Do NOT use for postoperative lab monitoring, routine lab review, or intraoperative lab management.
