Test Overview & Methodology
The Williams Syndrome (FISH) test uses fluorescence in situ hybridization (FISH) to detect the deletion of the elastin gene locus at chromosome 7q11.23, the hallmark of Williams syndrome. This targeted approach delivers the highest clinical sensitivity compared to genome-wide platforms and is the gold standard for confirmation.
| Feature | Our Williams Syndrome (FISH) Test | Closest Alternative (Chromosomal Microarray) |
|---|---|---|
| Precision | >99.9% sensitivity and specificity for the 7q11.23 microdeletion | High resolution genome-wide; may detect incidental findings |
| Methodology | Fluorescence In Situ Hybridization (FISH) – gold‑standard targeted probe | Array‑comparative genomic hybridization (aCGH) |
| Turnaround Time | 3–4 days | 7–14 days |
| Price | 700 AED | 1,800–2,500 AED |
Physician Insight & Safety Protocols
“As a Consultant Medical Genetics specializing in chromosomal disorders, I confirm that FISH for Williams syndrome is the most reliable method to detect the 7q11.23 deletion. A positive result must be integrated with a full clinical evaluation, including echocardiography and developmental assessment. No test replaces the need for expert medical follow-up; I advise all patients to discuss results within a multidisciplinary care team.”

Patient Advisory
⚠️ Medication Warning
Do not discontinue or alter any prescribed medication without consulting your physician. Genetic testing results do not replace ongoing medical management or current treatment plans. Always follow your doctor’s advice.
Safety Exclusion Criteria & Emergency Red Flags
- Active bleeding disorder or severe thrombocytopenia (platelets <50,000/µL) – postpone collection until stabilized.
- Recent blood transfusion (<2 weeks) may interfere with FISH analysis; reschedule as advised.
- Uncooperative patient or inability to provide informed consent; legal guardian required for minors.
- Pregnant women requiring amniotic fluid collection: must have clearance from an obstetrician.
🚨 If the patient experiences chest pain, fainting, sudden severe headache, or severe shortness of breath, seek emergency care immediately. These symptoms may indicate a cardiovascular complication associated with Williams syndrome.
Patient FAQ & Clinical Guidance
1. What exactly does the Williams Syndrome FISH test look for?
This FISH test detects the 7q11.23 deletion that confirms Williams syndrome, offering a highly definitive genetic diagnosis. The targeted probe hybridizes to the elastin gene locus, revealing the characteristic microdeletion present in over 99% of classical cases.
2. Do I need a doctor’s prescription for this test?
Yes, you must provide a prescription from a DHA-licensed doctor. We assist with verification via WhatsApp. In compliance with UAE Federal Decree-Law No. 4 of 2016 on Medical Liability, genetic testing for minors requires parental consent and a valid medical order.
3. How is the home blood collection procedure conducted?
Our DHA-certified phlebotomist visits your home, draws blood safely, and transports it in a specialized cold-chain. The visit can be scheduled between 8 AM and 11 PM, and the sample reaches our ISO-accredited laboratory within two hours, ensuring sample integrity.
4. How long does it take to get results?
The turnaround time is 3–4 days from sample receipt. Results are delivered via secure electronic report, and a consultant medical geneticist is available for telephonic interpretation.
