Pre-Surgical, Pre-Operative Clearance

The purpose of the pre-operative or pre-surgical clearance is to evaluate the patient’s overall health to detect any undiagnosed co-morbid conditions and to prepare the patient for treatment. The preoperative medical evaluation assists doctors in determining whether the patient is suitable for the proposed surgery based on the patient’s risk category, as well as identifying factors that may reduce the patient’s risk of complications.

What pre-operative lab tests are necessary before the surgery?

The healthcare providers suggest selective testing in certain instances, such as in individuals with underlying diseases or risk factors that enhance their risk of surgical problems. These tests should also be performed in high-risk surgical operations. These tests include the following:

  • Complete blood count (CBC)
  • Renal function test (RFT)
  • Electrolytes
  • Blood glucose
  • Liver function tests
  • Hemostasis tests
  • Urinalysis
  • Pregnancy tests
  • Electrocardiogram (EKG)
  • Chest radiograph (Chest X-Ray)
  • Pulmonary function test (PFT)
