Glucagon Lab Test – Accurate Hormone Level Testing for Diabetes & Metabolic Health

The Glucagon Lab Test from Lab Tests Dubai is a highly specialized blood test that measures levels of glucagon, a hormone produced by the alpha cells of the pancreas that plays a critical role in blood sugar regulation.

While insulin lowers blood glucose, glucagon raises it by signaling the liver to release stored glucose—ensuring energy balance during fasting or stress.

This test is essential for:

• Diagnosing glucagonoma, a rare neuroendocrine tumor of the pancreas
• Investigating unexplained hyperglycemia or diabetes
• Evaluating recurrent hypoglycemia (especially in insulinoma workup)
• Assessing metabolic disturbances in critically ill patients

Due to glucagon’s instability in blood, the test requires specialized sample collection using EDTA plasma with aprotinin(a protease inhibitor) to prevent degradation.

Results are typically available within 7–10 days, with samples processed in reference laboratoriesusing radioimmunoassay (RIA) or ELISA methods.

Available with home blood collection and on-site phlebotomy support, Lab Tests Dubai ensures accurate, timely, and stress-free testing—so you can get answers for complex metabolic conditions.

Why You Need This Test

If you’re experiencing mysterious rashes, unexplained weight loss, or blood sugar issues, this test could reveal a rare but treatable pancreatic tumor.

You need the Glucagon Test if:

• You have necrolytic migratory erythema (a distinctive rash on groin, legs, or mouth)
• You’re losing weight despite normal/elevated appetite
• You have new-onset or difficult-to-control diabetes
• You experience chronic diarrhea or anemia without cause
• You’re being evaluated for pancreatic neuroendocrine tumors (PNETs)
• You have a family history of MEN1 syndrome (Multiple Endocrine Neoplasia Type 1)

Glucagonoma is extremely rare (1 in 20 million), but 90% of cases are malignant—making early diagnosis life-saving.

This test is not routine—it’s for targeted evaluation of red-flag symptoms.

Symptoms That Indicate This Test

Consider the Glucagon Test if you experience:

• For Glucagonoma (4 “D” Syndrome):

• Dermatitis – red, blistering rash (necrolytic migratory erythema)

• Diabetes – new or worsening hyperglycemia

• Deep vein thrombosis (DVT) – high clotting risk

• Diarrhea – watery, chronic

• Weight loss & anemia

• For Metabolic Imbalance:

• Frequent hypoglycemia (with low insulin/C-peptide)

• Unexplained hyperglycemia despite treatment

• Fatigue, weakness, or confusion from glucose swings

• For Pancreatic Mass:

• Incidental finding on CT/MRI/EUS

• Family history of MEN1 or PNETs

These signs may point to pancreatic hormone dysfunction—and this test helps confirm or rule out glucagonoma.

Natural Production: How Glucagon Regulates Blood Sugar

Glucagon is produced by alpha cells in the pancreatic islets and works opposite to insulin:

• Low blood sugar → Glucagon ↑ → Liver releases glucose
• High blood sugar → Glucagon ↓

Elevated Glucagon May Indicate

• Uncontrolled Type 1 or 2 Diabetes (relative excess)
• Liver disease (reduced clearance)
• Critical illness or starvation

Low Glucagon

• Hypoglycemia (especially post-prandial)
• Type 1 Diabetes (loss of alpha cell function)
• Pancreatectomy or chronic pancreatitis

This test is often paired with insulin, C-peptide, and chromogranin A for full endocrine workup.

What Happens If Untreated? Risks of Ignoring High Glucagon

Ignoring high glucagon levels can lead to:

• Metastatic Glucagonoma – spreads to liver, lymph nodes
• Severe Malnutrition – from chronic diarrhea and protein loss
• Life-Threatening DVT or Pulmonary Embolism
• Uncontrolled Diabetes & Wound Healing Issues
• Debilitating Skin Lesions – painful, recurrent rashes

The good news? Glucagonoma is treatable with:

• Surgical resection (if localized)
• Somatostatin analogs (e.g., octreotide)
• Peptide Receptor Radionuclide Therapy (PRRT)
• Chemotherapy (for advanced cases)

Early testing = earlier diagnosis, better survival.

How to Prepare for the Test

To ensure accurate results:

• Fast for 8–12 hours (overnight fast)

• Avoid alcohol and heavy meals 24 hours before

• Inform your doctor of:

• Diabetes medications (insulin, GLP-1 agonists)

• Recent illness or surgery

• Use of somatostatin analogs (e.g., octreotide – can suppress glucagon)

  • Special Collection Required:

• Blood must be drawn into EDTA tube with aprotinin (inhibits glucagon breakdown)

• Immediately chilled and centrifuged within 30 mins

• Frozen plasma shipped to reference lab

Our trained phlebotomists are equipped to handle specialized hormone collections—ensuring sample integrity.
