Laboratory Medicine Summary

Preoperative testing should include, at a minimum, a complete blood count (CBC), a comprehensive metabolic panel, and a blood type and screen. Prothrombin time (PT) and partial thromboplastin time (PTT) are not routinely necessary. A carcinoembryonic antigen (CEA) level should be obtained prior to resections of colon adenocarcinomas.
