Sample Stability
- Hemolyzed or lipemic samples
- Insufficient sample volume
- Improper labeling or storage
- Sample older than stability period
Understanding Your Results
Negative
No detectable antibodies; insulinoma is less likely, but further tests may be needed based on symptoms.
Positive
Antibodies detected; supports diagnosis of insulinoma. Consult an endocrinologist for confirmatory tests like imaging.
Equivocal
Borderline results; repeat testing or additional evaluation recommended.
If you experience recurrent hypoglycemia symptoms or have a positive test result, consult an endocrinologist immediately for further evaluation and management.
Limitations
- ⚠Cannot confirm insulinoma alone; requires correlation with imaging and clinical symptoms
- ⚠May have cross-reactivity with other autoantibodies
- ⚠Not suitable for monitoring treatment response

- ●Minor pain or bruising at the puncture site
- ●Rare risk of infection or fainting
- ●No significant long-term risks
Interfering Factors
- ●Recent infections or autoimmune conditions
- ●Use of immunosuppressive medications
