What blood tests are done before gastric bypass?

Before gastric bypass surgery, several blood tests are typically conducted to assess the patient's overall health and identify any potential issues. Common tests include complete blood count (CBC) to check for anemia, metabolic panel to evaluate kidney and liver function, and tests for vitamin deficiencies, such as vitamin B12 and iron levels. Additionally, tests for blood clotting factors and screening for infections may also be performed to ensure safe surgical outcomes. These tests help guide preoperative care and postoperative nutritional planning.
