If you are looking for a Chromogranin A blood test in Chandigarh, Altus Lab offers this specialist neuroendocrine tumour marker with free home collection across Chandigarh, Mohali, and Panchkula. Chromogranin A (CgA) is a glycoprotein secreted by neuroendocrine cells throughout the body. Elevated Chromogranin A is the most sensitive and widely used blood marker for neuroendocrine tumours (NETs) — a diverse group of cancers that can arise in the gut, pancreas, lung, adrenal gland, and other sites.
Our lab is founded and led by an Ex-PGIMER Chandigarh doctor with over 13 years of specialist diagnostic experience. Because we operate our own in-house laboratory, we process every sample on-site with direct specialist oversight. Most Chromogranin A results are consequently ready within 24–48 hours. Doctors at PGIMER, GMCH-32, Fortis Mohali, and Max Hospital accept our reports for oncology follow-up.
What Are Neuroendocrine Tumours (NETs)?
Neuroendocrine tumours are a heterogeneous group of neoplasms that arise from neuroendocrine cells — cells with both nerve and hormone-secreting properties. They can be functional (secreting hormones that cause symptoms) or non-functional (growing silently without hormonal symptoms). Because NETs often present with vague symptoms — flushing, diarrhoea, abdominal pain, wheezing — they are frequently misdiagnosed for years. Chromogranin A is therefore a critical early diagnostic tool.
What Does Chromogranin A Measure?
| Parameter | Detail |
|---|---|
| What it is | A secretory protein co-released with catecholamines and peptide hormones from neuroendocrine cells |
| What elevated CgA indicates | Neuroendocrine tumour activity — carcinoid tumours, pancreatic NETs, phaeochromocytoma, paraganglioma, small cell lung cancer |
| Normal range | <100 ng/mL (varies by laboratory methodology) |
| Clinical use | Diagnosis, treatment monitoring, and recurrence surveillance in NET patients |
| False elevations | Proton pump inhibitor (PPI/omeprazole) use, renal failure, heart failure, chronic atrophic gastritis |
Who Should Get a Chromogranin A Test in Chandigarh?
- Patients with unexplained flushing episodes, profuse watery diarrhoea, or wheezing — classic carcinoid syndrome symptoms
- Patients with an incidentally discovered mass in the pancreas, intestine, or lung on imaging
- Known NET patients for treatment response monitoring and surveillance
- Patients with episodic headaches, sweating, and hypertension — to screen for phaeochromocytoma
- Patients referred by gastroenterologists, endocrinologists, or oncologists at PGIMER or Fortis Mohali
- Patients with unexplained weight loss, fatigue, or abdominal pain with no clear diagnosis after standard investigations
Chromogranin A Alongside Other NET Markers
For the most complete neuroendocrine tumour workup, Chromogranin A should ideally be tested alongside:
- 24-hour Urine 5-HIAA — elevated in serotonin-secreting carcinoid tumours
- NSE (Neuron-Specific Enolase) — marker for high-grade NETs and small cell lung cancer
- Synaptophysin — tissue marker used in histopathology after biopsy
- Gastrin, VIP, Glucagon, Insulin — for specific pancreatic NETs depending on clinical presentation
Altus Lab can coordinate a comprehensive NET marker panel based on your specialist’s recommendation. Please bring your referral letter from your gastroenterologist or oncologist at PGIMER Chandigarh when booking.
Important: Drugs That Affect Chromogranin A Levels
Proton pump inhibitors (PPIs) such as omeprazole, pantoprazole, and rabeprazole — which are among the most commonly prescribed medications in India — can significantly elevate Chromogranin A levels, causing false-positive results. If you are taking a PPI, your doctor may advise stopping it for at least 2 weeks before testing. Always inform your doctor and our laboratory staff about your current medications before getting this test.

Frequently Asked Questions — Chromogranin A Test in Chandigarh
Do I need to fast before the Chromogranin A test?
Fasting is not strictly required for Chromogranin A testing. However, because eating can slightly influence levels, a 4-hour fast before the test is generally recommended. More importantly, if you are taking PPIs (omeprazole, pantoprazole), consult your doctor about whether to temporarily stop them before testing to avoid false elevation.
My Chromogranin A came back elevated. Does that mean I have a NET?
Not necessarily. Chromogranin A can be elevated in many benign conditions — particularly PPI use, renal failure, heart failure, and chronic atrophic gastritis. Your gastroenterologist or oncologist will correlate the CgA result with imaging findings, symptoms, and other markers before reaching any conclusion. An elevated CgA without any other evidence of disease should be re-tested after stopping PPIs if applicable.
Can this test be done at home in Chandigarh?
Yes. Altus Lab provides free home sample collection for the Chromogranin A test across Chandigarh, Mohali, and Panchkula. Call 0172-5017001 or WhatsApp us to book a convenient slot. Please inform us at the time of booking about any PPIs or other medications you are taking.
