Depending on various other factors, you may be asked to undergo a pre-admission testing with the hospital before your surgical procedure. This mainly depends on the age of the patient, the type or particular procedure performed, certain risk factors, or requirements of the hospital or clinic or the anesthesiologist. Your surgeon will let you know if pre-admission testing is required in your case. Typically, pre-admission testing requires the patient to report to the hospital several days before a scheduled surgery procedure for simple lab work and diagnostics. You will also have to pre-register for your surgery at that point.
