Overview
Laboratory tests used in the diagnosis of VIPoma include serum vasoactive intestinal polypeptide (VIP) levels, basal gastric acid output, potassium, bicarbonate, magnesium, and calcium levels.[1][2]
Laboratory Findings
Laboratory findings consistent with the diagnosis of VIPoma include:[1][2]
- Serum vasoactive intestinal polypeptide (VIP) levels. Normal fasting serum VIP level is generally < 75pg/ml whereas VIPomas have levels generally > 500pg/ml.[3]
- Pancreatic polypeptide levels and neurotensin levels
- Low serum potassium, bicarbonate, and magnesium levels secondary to fecal loss
- High calcium levels secondary to fecal loss
- Low basal gastric acid output
