Test Overview & Methodology
Chromogranin A (CgA) Immunohistochemistry (IHC) testing is the gold-standard tissue biomarker to confirm neuroendocrine differentiation in solid tumors. This test uses validated monoclonal antibodies on formalin-fixed, paraffin-embedded (FFPE) tissue, delivering definitive evidence for neuroendocrine neoplasms. The procedure employs DAB chromogen detection on automated staining platforms with strict internal quality controls per CAP guidelines.
| Feature | Chromogranin A IHC (450 AED) | Serum CgA ELISA (Alternative) |
|---|---|---|
| Precision | Tissue-specific, high diagnostic specificity above 98% | Variable sensitivity approximately 70%, affected by renal function and PPI use |
| Methodology | Immunohistochemistry (IHC) on FFPE block with validated antibody clone | Enzyme-linked immunosorbent assay (ELISA) from peripheral blood |
| Turnaround Time | 5 to 7 business days (complex cases up to 7 days) with same-day pickup by 6 PM | 1 to 2 days, but cannot localize tumor origin or provide tissue context |
Physician Insight & Safety Protocols
Mr. Prabhakar Reddy Kalathoor | Specialist Diagnostic Radiology | DHA Registration ID: 61713011
As a diagnostic imaging specialist, I recommend interpreting Chromogranin A IHC results strictly within the full context of histomorphology and clinical history. A positive result confirms neuroendocrine origin but never replaces comprehensive oncologic workup including cross-sectional imaging and biochemical profiling. Clinical correlation remains essential for accurate staging and treatment planning.
Clinical Advisory Notice
Do not discontinue prescribed medication without consulting your doctor. This test does not replace clinical follow-up or treatment decisions. Patients should continue all prescribed therapies unless otherwise directed by their treating physician.
Exclusion Criteria & Emergency Red Flags
- Test requires tissue biopsy specimen (FFPE block or formalin-fixed tissue). Not applicable for liquid cytology, serum, or plasma samples.
- Do not send specimens with unknown fixative or without accompanying histopathology report; incomplete documentation will delay reporting.
- Seek emergency care immediately if you experience sudden rapid tumor swelling, severe pain, or neurological changes while awaiting results.
- This IHC panel is not designed for screening purposes; clinical correlation with imaging and laboratory data is mandatory for diagnostic interpretation.
Patient FAQ & Clinical Guidance
1. What does a positive Chromogranin A IHC test mean for my diagnosis?
A positive Chromogranin A IHC stain indicates that your tumor cells express neuroendocrine secretory proteins, strongly suggesting a neuroendocrine neoplasm. This finding must be integrated with the complete histopathology report, clinical presentation, and radiological findings for accurate diagnosis and management planning.
2. How should I prepare for a Chromogranin A IHC tissue test in the UAE?
No patient fasting or medication adjustments are required for this test. Simply ensure your biopsy sample is submitted in 10% neutral-buffered formalin or as an FFPE block along with the complete histopathology report and relevant clinical history. Our medical courier team coordinates retrieval directly with your healthcare facility.
3. Is the Chromogranin A IHC test covered by health insurance in the UAE?
Most UAE insurance plans cover this test when coded with ICD-10-CM C7A.1 (malignant neuroendocrine tumor) and pre-approval is obtained. Our billing team verifies coverage instantly via WhatsApp at +971 54 548 8731. Prior authorization may be required depending on your insurance provider and policy terms.
4. How is the tissue sample collected for Chromogranin A IHC testing?
The sample is obtained through a biopsy procedure performed at a hospital or accredited medical facility. The extracted tissue is fixed in formalin and embedded in paraffin to create an FFPE block. Our secure medical courier service retrieves the prepared specimen from the collecting facility under temperature-controlled conditions and transports it to our CAP-accredited laboratory for processing.
