A blood serum glucagon concentration of 1000 pg/mL or greater is indicative of glucagonoma (the normal range is 50-200 pg/mL).
Blood tests may also reveal abnormally low concentrations of amino acids, zinc, and essential fatty acids, which are thought to play a role in the development of NME. Skin biopsies may also be taken to confirm the presence of NME.
A CBC can uncover anemia, which is an abnormally low level of hemoglobin.
The tumor itself may be localized by any number of radiographic modalities, including angiography, CT, MRI, PET, and endoscopic ultrasound. Laparotomy is useful for obtaining histologic samples for analysis and confirmation of the glucagonoma.
