Clinical guidelines recommend a thorough nutritional assessment for all individuals before and after bariatric surgery, and guidance varies based on the type of procedure. The ARUP Consult Bariatric Surgery - Nutritional Assessment topic provides updated information on pre- and postoperative nutrient testing for procedures such as sleeve gastrectomy, Roux-en-Y gastric bypass, and biliopancreatic diversion with duodenal switch.

Respiratory Viruses

Laboratory testing to identify the specific pathogen causing a respiratory illness is only necessary if clinical management would be altered. The ARUP Consult Respiratory Viruses topic details when this testing might be warranted and in which populations testing is indicated to inform patient management, epidemiologic surveillance, and infection control measures.

Alpha-1-Antitrypsin Deficiency Testing

Alpha-1-antitrypsin (AAT) deficiency, an inherited disorder associated with lung and liver disease, is the most common nonenvironmental cause of emphysema and is the fourth most common indication for lung transplantation worldwide. Severe AAT deficiency may cause improper folding of the AAT protein, leading to deposition in hepatocytes and corresponding liver disease. The ARUP Consult Alpha-1-Antitrypsin Deficiency Test Fact Sheet details the different purposes of phenotyping, genotyping, and serum/plasma testing.
