Blood insulin level. Diagnosis by blood sugar and Insulin levels in the blood. Low blood sugar with high Insulin confirms diagnosis. To detect the tumor in the pancreas, (most are small), so detection may be difficult; studies performed, fine cut ct scan, mri, octreotide scan, and/or endoscopic ultrasound. Surgeons detect these tumors even where they are not seen on radiological testing with ultrasound during surgery.
Blood tests. Functioning insulinomas produce Insulin and lead to low blood sugar (glucose) levels. Blood tests will generally show a low glucose level and a high Insulin level. These tumors are usually located in the pancreas, but may rarely occur elsewhere in the body. Body scans (cat scan or other) can determine the site of the tumor.
Blood and imaging. Insulinoma is diagnosed with blood tests and imaging. Fasting levels of c-peptide, Insulin and glucose are done. Ct scan or MRI can determine if a pancreatic mass is present. Endoscopic ultrasound is also useful for imaging abd obtaining tissue for diagnosis.
LAB AND XRAY. An insulinoma is a tumour of the pancreas that secrets insulin, driving a patients' blood glucose low, since the normal feeback mechanism is overridden. Blood tests - insulin, glucose, c-peptide, and proinsulin - would be done to make such a diagnosis. Radiologic investigation can include ct, mri, ultrasound, and, occasionally, angiography (blood vessel dye study.) good luck.
