Which statement best describes how preoperative laboratory testing should be determined for outpatient procedures?

• A. Routine for all outpatient procedures
• B. Tests should be limited to those that influence management and are indicated by risk
• C. Only tests if surgeon requests
• D. Testing is unnecessary

Answer: (B)

Selective preoperative laboratory testing is driven by whether the results would change how the patient is managed during the perioperative period. In practice, this means avoiding routine labs for every outpatient and instead ordering tests only when the patient’s risk factors, comorbidities, or the planned procedure's physiologic stress make a lab result capable of altering management. For a healthy individual undergoing a low‑risk outpatient procedure, no baseline tests may be needed. In contrast, someone with known medical conditions, those on medications affecting coagulation or organ function, or procedures that carry higher anesthesia or bleeding risk warrant targeted tests to guide optimization, medication adjustments, or postoperative planning. The key idea is that testing should be indicated by its potential to influence decisions, not simply by habit or request. A surgeon’s request can be reasonable, but it should still meet the criterion of changing management. Routine testing for all outpatients is unlikely to improve outcomes and can cause unnecessary delays or follow-up.
