Routine blood work and lab orders are vital to maintaining good health following Duodenal Switch weight loss surgery. Everyone's body is different and by examining your blood work and adjusting your vitamin and mineral supplements and protein intake you will not only be healthier, but you will also be able to earlier detect any potential problems that may occur.

Your surgeon will have his or her own list of recommended blood work and lab orders. Be sure to follow your surgeon's guidelines and send the results to your surgeon for evaluation.

For informational purposes only there are lists of blood work and lab orders from various sources to follow.
