Blood Work and Lab Orders
Routine blood work and lab orders are vital to maintaining good health following the Duodenal Switch weight loss surgery. Everyone’s body is different and by examining the blood work and adjusting vitamin, mineral supplements and protein intake a patient will not only be healthier, but will also be able to detect any potential problems that may occur.
The surgeon will have his or her own list of recommended blood work and lab orders. Be sure to follow the surgeon’s guidelines and send the results to the surgeon for evaluation.
For informational purposes only there are lists of blood work and lab orders from various sources to follow.
