Overview
Laboratory findings consistent with the diagnosis of glucagonoma include a serum glucagon concentration of 1000 pg/ml or greater.
Laboratory Findings
The laboratory findings associated with glucagonoma are:[1][2][3]
Serum glucagon
- Increased plasma glucagon levels >500 pg/mL (Normal glucagon level is less than 50 pg/mL).
- Concentrations above 1000 pg/mL are diagnostic of glucagonoma.
- Some conditions can increase glucagon level to a level less than 500 pg/mL such as fasting and hypoglycemia.
- Some symptomatic glucagonomas are associated with normal glucagon serum level. So, a serum glucagon concentration below 500 pg/mL does not exclude a glucagonoma.[3]
Other laboratory findings
- Blood tests may also reveal low concentrations of amino acids, zinc, and essential fatty acids.
- A complete blood count (CBC) to diagnose anemia.
