Chromosomal Microarray (CMA) 750K High Resolution in UAE | 2800 AED | DHA Licensed
Executive Summary & Core Metrics
Executive Summary: Chromosomal Microarray (CMA) 750K High Resolution delivers 99.9% diagnostic sensitivity for submicroscopic chromosomal imbalances using Affymetrix CytoScan 750K technology. Conducted under ISO 9001:2015 and DHA directives, the test includes VIP mobile phlebotomy & temperature-controlled cold-chain home collection, direct billing verification via WhatsApp, and telephonic post-test clinical guidance.
Test Overview & Methodology
The Chromosomal Microarray (CMA) 750K High Resolution test scans the entire genome for clinically significant copy number variations (CNVs) using 750,000 single nucleotide polymorphism (SNP) markers. This advanced technique often reveals diagnoses for intellectual disability, autism, congenital anomalies, and prenatal genetic conditions when standard karyotype fails.
The assay utilizes Affymetrix CytoScan 750K SNP Microarray combined with Optima Suite analysis software, providing genome-wide coverage at a resolution exceeding 100 times that of conventional karyotyping.
| Feature | Our CMA 750K (DHA Compliant) | Closest Alternative (Low-Density CMA) |
|---|---|---|
| Resolution | 750,000 SNPs | 60,000–180,000 SNPs |
| Detection Rate for Pathogenic CNVs | 99.9% | ~85–90% |
| Methodology | Affymetrix CytoScan 750K SNP Microarray + Optima Suite | BAC/CGH Array |
| Turnaround Time | 15 working days | 21–28 days |
Physician Insight & Safety Protocols
“As a DHA-licensed Consultant Medical Genetics, I emphasize that CMA results are a powerful diagnostic tool but must always be interpreted alongside a thorough clinical evaluation. Do not make treatment or reproductive decisions based solely on this report—consult your specialist to understand the full picture.” — Lina Osama Zaki Quteineh, Consultant Medical Genetics, DHA Registration ID: 9294403
Clinical Advisory: Pre-Test Genetic Counseling
Patients are advised to undergo pre-test genetic counseling with a qualified specialist prior to sample collection. This ensures informed consent and clarity regarding the scope, limitations, and potential incidental findings of the chromosomal microarray analysis. The consent form must be signed and witnessed in compliance with Federal Decree-Law No. 4 of 2016 on Medical Liability.
Exclusion Criteria & Emergency Red Flags
- Recent Blood Transfusion: Avoid CMA testing within 4 weeks of transfusion to prevent donor DNA contamination.
- Severe Anemia or Leukopenia: Phlebotomy risk; require physician clearance before collection.
- Known Chimerism: May cause ambiguous CNV calls; special pre-analytical protocol required.
- Prenatal Samples < 10 Weeks Gestation: Ensure chorionic villus sampling is accompanied by formal genetic counseling.
- Acute Neurological or Bleeding Emergency: If the patient experiences sudden loss of consciousness, seizure, or uncontrolled hemorrhage, go directly to the emergency department—this test is not for acute care.
Patient FAQ & Clinical Guidance
1. What can the 750K microarray detect that a karyotype cannot?
The 750K microarray identifies submicroscopic deletions, duplications, and regions of homozygosity at over 100 times the resolution of a conventional karyotype, making it essential for pinpointing microdeletion syndromes (e.g., 22q11.2, 16p11.2) and cryptic chromosomal rearrangements.
2. How should I prepare for the blood collection?
No fasting or special preparation is needed; simply ensure the Genomic Microarray Requisition Form (Form 19) is fully completed and signed by your ordering physician to avoid processing delays.
3. When will I receive my results and who will explain them?
Results are available within 15 working days; our DHA-licensed genetic counseling team provides a complimentary post-test clinical guidance call to review findings and recommend next steps.
4. Is the test covered by health insurance in the UAE?
Coverage varies by insurer. Our billing team can verify your eligibility and assist with pre-authorization. Contact us via WhatsApp for a direct assessment.
