The preoperative test package is a set of comprehensive medical examinations conducted before any surgical procedure or prenatal operations to ensure the patient's health and safety. This package includes important tests to detect viral infections such as hepatitis B and C, a complete blood analysis to measure sugar and glucose levels, in addition to other tests such as blood creatinine level, liver function, coagulation time, and urine analysis. Through these tests, the body's readiness for surgery is confirmed and any potential health risks are identified to ensure the procedure proceeds smoothly.
