What are some of the usual tests before surgery?

A complete blood count (CBC), urinalysis, and a chemistry panel which gives us a readout of about 20 blood chemistry values. Most people, except the very young, get a chest X-ray and an electrocardiogram. We may do a gallbladder ultrasound to look for gallstones. Other tests which we frequently order, when indicated, include pulmonary function testing, echocardiogram, sleep studies, GI evaluation, or cardiology evaluation.
