Tests Before Surgery: Preoperative Checklist
Tests Before Surgery

Which tests are required before surgery?

Before planned surgery, patients undergo a preoperative assessment. It helps the clinical team evaluate general health, identify risks and prepare an individual perioperative plan.

The standard assessment includes blood and urine tests, coagulation studies, blood chemistry and instrumental examinations such as an ECG and chest X-ray. Additional investigations may be required depending on age, medical history and the planned procedure.

The list below reflects the clinic’s current admission requirements. Confirm it with your coordinator because requirements and validity periods may change.
