HLA Cadaveric Crossmatch Test in UAE | 1200 AED | DHA Licensed

Executive Summary & Core Metrics

The HLA Cadaveric Crossmatch detects preformed donor-specific antibodies in recipient serum against cadaveric donor lymphocytes using Complement Dependent Cytotoxicity (CDC) with DTT treatment. This assay is the gold-standard pre-transplant evaluation for kidney, liver, and multi-organ recipients, preventing hyperacute rejection and ensuring only compatible grafts proceed to transplantation.

Accuracy: 99.9% diagnostic sensitivity via ISO-accredited processing (Cert: INT/EGQ/2509DA/3139).
Logistics: Hospital Extraction Only – Sample collection is conducted strictly within an accredited hospital facility; mobile home phlebotomy is disabled for safety.
Clinical Guidance: Post-test telephonic result interpretation by a DHA-licensed general practitioner.
Insurance: Direct billing verification through WhatsApp +971 54 548 8731 (8 AM – 11 PM).

Test Overview & Methodology

The CDC-DTT crossmatch method identifies clinically significant IgG antibodies while eliminating IgM interference through dithiothreitol (DTT) treatment. This ensures that only donor-specific antibodies capable of triggering complement-mediated rejection are detected, reducing false-positive results that could unnecessarily exclude life-saving organs.

Feature	CDC-DTT Crossmatch	Flow Cytometry Crossmatch (FCXM)
Testing Principle	Complement-mediated lysis; DTT removes IgM interference	Fluorescent detection of bound antibodies
Specificity	High for clinically significant IgG	Higher sensitivity, but may yield false-positive IgM signals
Turnaround Time	10–12 working days	5–7 working days
Cost (AED)	1200	~1500

CDC-DTT remains the DHA-preferred method for cadaveric donor evaluation, minimizing false-positive results that could unnecessarily exclude life-saving organs.

Physician Insight & Safety Protocols

“Every crossmatch result carries the weight of a potential second chance at life. Our CDC-DTT protocol has been refined through decades of transplant evidence to deliver the highest specificity for clinically relevant antibodies. We handle each specimen with the rigorous attention it deserves, so you can proceed to transplantation with confidence.” – Dr. Ajay Singh, General Practitioner (DHA License 36234132)

Medication and Clinical Advisory

Important Clinical Advisory

Do not discontinue any prescribed immunosuppressive or transplant-related medication without explicit guidance from your transplant physician. This test provides immunological risk stratification and must be interpreted within the full context of your clinical history and current treatment regimen.

Exclusion Criteria & Emergency Red Flags

Active systemic infection or febrile illness at time of collection.
Recent blood transfusion within 72 hours that may introduce allogeneic lymphocytes.
Severe lymphopenia or ongoing immunosuppressive therapy that compromises lymphocyte viability.
Emergency Red Flags: Seek immediate emergency care if you experience chest pain, difficulty breathing, severe abdominal pain, or signs of anaphylaxis before or after sample collection.

Patient FAQ & Clinical Guidance

1. Why is an HLA crossmatch required before cadaveric kidney transplantation?

The HLA crossmatch detects donor-specific antibodies that can trigger immediate hyperacute rejection. A negative result confirms immunological compatibility, allowing the transplant to proceed with the highest chance of graft survival.

2. How does DTT treatment improve the accuracy of the crossmatch?

DTT selectively breaks down IgM antibodies, revealing only IgG antibodies that are clinically significant for chronic rejection risk and long-term graft outcome. This reduces false-positive results that could block a life-saving transplant.

3. Is home sample collection available for this test?

No. Due to the involvement of cadaveric donor tissue, all samples must be collected within an accredited hospital facility. Our team coordinates directly with the hospital to ensure proper specimen handling and cold-chain transport to the laboratory.

4. What pre-requisites are required before sample collection?

A doctor’s prescription on official letterhead with stamp and a photograph of the recipient is mandatory. Recipient specimens should ideally be collected 48 hours after dialysis. Cadaveric donor samples must be shipped refrigerated and never frozen. Full clinical instructions will be provided at booking.
