Dr. Stephen Southard answered

Specializes in Internal Medicine

Depends: GI issues can cause hypokalemia like diarrhea or vomiting. False positives for chromogranin A can be related to PPI use like omeprazole, as can pernicious anemia, kidney and/or liver issues. False positive VIP levels can be from fasting, small bowel surgeries, and kidney disease but also elevated in inflammatory bowel disease.
