Pre-admission Testing During pre-admission testing, all your necessary tests will be performed or scheduled and information will be gathered to prepare for your surgery. It usually takes place one to two weeks before your surgery.1,–3 Tests that are commonly performed: Blood tests Common blood tests performed before surgery include a complete blood count (CBC),3 which measures the components of your blood including the number of red and white blood cells, hemoglobin, and hematocrit.4 Other common blood tests include checking your blood sugar level, and your kidney and liver function.3 Additional tests Other tests your surgeon may ask you to have, if you have not had them recently, include an electrocardiogram (EKG),3 which shows how well your heart is working,5 and a chest X-ray.3 Other tests that may be needed: Depending upon certain factors such as your age and general health, the presence of preexisting health problems, and the type of surgery you are having, your surgeon may order other tests before surgery, including:3 Colonoscopy or upper endoscopy to check the lining of your bowels or stomach Heart stress test or other heart tests Lung function tests Imaging tests such as a magnetic resonance imaging (MRI) scan, a computed tomography (CT) scan, or an ultrasound Prepare for Your Pre-Admission Testing What to bring to pre-admission testing:6 Insurance information List of your medications Copy of your living will or power of attorney for health care, if you have one Meeting your anesthesiologist: You may meet the anesthesiologist (the doctor responsible for “putting you to sleep” or numbing you during surgery) and a nurse who will discuss your health history with you and make sure that you are ready for surgery.1,7,8 The anesthesiologist will also discuss the type of anesthesia (medication that numbs the area or puts you to sleep).8 Depending upon your particular circumstances, your interview with the anesthesiologist may be very brief.7 Important Tip: Tell the nurse or the doctor about any allergies or reactions you have had to medications or anesthesia in the past.9 Instructions for the day of surgery The nurse will give you instructions for your surgery, such as which medications to take the day of surgery and not to eat or drink anything after midnight, the night before the surgery. 8 References 1.
