Which lab result should be reported to the surgeon as it could lead to postponement of surgery?

A hemoglobin level of 8.0 g/dL is a significant finding that warrants immediate attention and could lead to postponement of surgery. Hemoglobin is a critical component in assessing a patient's ability to adequately transport oxygen in the blood. A level of 8.0 g/dL is indicative of anemia, which can increase the risk of complications during and after surgery, such as inadequate oxygenation, increased need for blood transfusions, and overall poor recovery. The surgical team must ensure that the patient’s hemoglobin level is within a safe range to minimize these risks before proceeding with any surgical intervention.

In contrast, a white blood cell count of 12,000/mm³, while slightly elevated and possible indication of infection or inflammation, may not immediately necessitate the postponement of surgery. A platelet count of 150,000/mm³ falls within the normal range, and a blood pressure of 120/80 mmHg is considered healthy. Thus, neither of these findings would typically cause a concern that would lead to rescheduling the procedure, unlike the critically low hemoglobin level.
