Chromogranin A (CGA) Test in Dubai – Neuroendocrine Tumor Marker | 1,500 AED
Executive Summary & Core Metrics
Test Overview & Methodology
Chromogranin A (CGA) is a highly specific serum biomarker used to detect and monitor neuroendocrine tumors (NETs). The test employs a high-sensitivity TRACE immunoassay on fully automated platforms, delivering same-day results when the specimen is received by 11 AM. This analyte is released by neuroendocrine cells and correlates with tumor burden, making it an essential tool for diagnosis, surveillance, and therapeutic response evaluation.
| Feature | CGA Test (Our Service) | Alternative – 5-HIAA Urine |
|---|---|---|
| Methodology | High-sensitivity TRACE immunoassay (fully automated) | Colorimetric HPLC / LC-MS/MS on 24-hour urine |
| Diagnostic Sensitivity | 99.9% (ISO-validated) | ~85–90% |
| Turnaround Time | Same day (sample by 11 AM) | 3–5 working days |
| Patient Convenience | Single blood draw; VIP mobile phlebotomy available | 24-hour urine container; requires refrigeration & preservatives |
| DHA & Regulatory Alignment | Fully compliant with DHA diagnostic standards | Alternative method; less standardised for routine NET surveillance |
Physician Insight & Safety Protocols
“As a Specialist Diagnostic Radiology (DHA: 61713011), I confirm that Chromogranin A is a robust serum marker for neuroendocrine tumor surveillance. However, its levels must always be interpreted alongside clinical history, imaging, and other laboratory parameters. Our laboratory ensures each result is communicated with clarity, and the complimentary telephonic guidance helps patients and referring physicians make informed next steps.”

Medication Advisory – Proton Pump Inhibitor Discontinuation
⚠️ Important Pre-Test Instruction
Proton pump inhibitors (e.g., omeprazole, esomeprazole, pantoprazole) can falsely elevate Chromogranin A levels. Your physician may advise a temporary 14-day washout period before blood collection. Do not stop any prescribed medication without explicit guidance from your treating doctor. Abrupt discontinuation may worsen gastroesophageal reflux or peptic symptoms; all changes must be medically supervised.
Exclusion Criteria & Emergency Red Flags
- Exclusion Criteria: Critically ill patients; active severe erosive esophagitis or peptic ulcer disease where PPI discontinuation poses clinical risk; known hypersensitivity to EDTA anticoagulant (rare); pregnancy – evaluate collaboratively with an obstetrician before testing.
- Age Restriction: For minors (under 18 years), parental or legal guardian consent is mandatory in accordance with Federal Decree-Law No. 4 of 2016 on Medical Liability.
- Emergency Red Flags – Seek Immediate Medical Attention if:
- You develop sudden severe abdominal pain, haematemesis (vomiting blood), or melena (black tarry stools) while off PPIs.
- You experience signs of carcinoid crisis: intense flushing, wheezing, severe diarrhoea, and a drop in blood pressure.
Patient FAQ & Clinical Guidance
1. Why is the Chromogranin A test performed?
Chromogranin A is a protein secreted by neuroendocrine cells. This blood test is primarily used to diagnose neuroendocrine tumors, monitor disease progression, and evaluate response to treatment. Elevated levels can indicate tumor presence or recurrence, guiding further imaging and therapeutic decisions.
2. How should I prepare before giving a blood sample?
You will likely need to temporarily discontinue proton pump inhibitor medications (such as omeprazole) for 14 days prior to collection, as these drugs can interfere with the assay. This washout must be done strictly under your physician’s supervision to avoid rebound symptoms. Fasting is not required, but your doctor may give specific instructions based on your health status.
3. Is home blood collection available for this test?
Yes, we provide VIP Mobile Phlebotomy and Temperature-Controlled Cold-Chain Home Collection across all seven emirates, operating daily from 8 AM to 11 PM. A trained phlebotomist will visit your residence or office, ensuring safe specimen handling and timely delivery to our ISO-accredited laboratory.
