The Major Pre-Op Profile is a comprehensive laboratory test performed before a major surgical procedure to evaluate a patient’s overall health. It provides essential insights to the surgeon and anesthesiologist about existing medical conditions, potential risks, and the patient’s ability to safely undergo surgery. This profile typically includes a complete blood count (CBC), a chemistry panel, and a coagulation panel, with additional specialized tests added based on the patient’s medical history and the type of surgery planned. By offering a detailed assessment of a patient’s health, the Major Pre-Op Profile plays a crucial role in ensuring safe and effective surgical care.
