Each doctor may have different requirements for blood tests, and this might vary based upon you overall medical history,
As per any other surgical procedure , you will be required CBC and other blood tests like glucose levels , Bun , Creatinine , Ast , Alt , coagulation tests , viral tests , urine test , chest X ray and cardiologist evaluation.( each doctor has their own routine ). it is important that all your parameters are normal , since this is an elective surgery.
