If PSs have a preference, they will specify the lab. Otherwise, either the PCP's lab or labcorp/quest can be used to perform the labs requested by your PS.Most surgeons will do some blood work prior to surgery, but some surgeons do not. It is always best to ask these questions of your chosen surgeon as recommendations may be different. The surgeon you select should know everything about your past medical and surgical history and be able to make a determination about what labs should be ordered, the need for EKG, the need for medical clearance, the need for anticoagulation, the appropriateness of the surgical intervention based upon the risk factors and current physique, etc.
