Clinical Test Overview

The FISH (Fluorescence In-Situ Hybridization) assay for chromosomes 13 and 22 is a targeted molecular cytogenetic test designed for the rapid detection of aneuploidies and microdeletions in prenatal amniotic fluid, chorionic villus samples, or postnatal blood specimens. This test provides critical diagnostic information for conditions including Patau syndrome (Trisomy 13) and 22q11.2 deletion syndrome (DiGeorge/VCFS), delivering actionable results within 10 to 12 working days.

يُعد تحليل FISH للكروموسومات 13 و22 اختباراً جينياً جزيئياً مستهدفاً للكشف السريع عن اختلال الصيغة الصبغية والحذف الميكروي في عينات السائل الأمنيوسي أو الزغابات المشيمية قبل الولادة أو عينات الدم بعد الولادة.

Physician Insight & Safety Protocol

Dr. PRABHAKAR REDDY (DHA License: 61713011), Consultant in Molecular Cytogenetics, states: "The FISH assay for chromosomes 13 and 22 provides rapid, targeted genetic information that must always be interpreted within the full clinical context. A negative FISH result does not exclude all chromosomal abnormalities, and a positive result should prompt comprehensive genetic counseling. I urge every patient to discuss results thoroughly with their referring physician before making any clinical decisions."

⚠ MEDICATION WARNING: Do not discontinue any prescribed medication or alter your treatment regimen without consulting your treating physician. This genetic test is diagnostic in nature and does not replace ongoing clinical management.

Exclusion Criteria & Emergency Red Flags

Exclusion Criteria (Do Not Proceed Without Physician Clearance)

Active vaginal bleeding in pregnancy (second or third trimester)
Suspected or confirmed placental abruption
Multiple gestation with uncertain chorionicity (for CVS sampling)
Documented maternal coagulopathy or anticoagulant therapy not yet cleared for invasive sampling
Known uterine anomaly that precludes safe amniocentesis access
Untreated maternal urinary tract infection or chorioamnionitis

Post-Procedure ER Red Flags – Seek Immediate Medical Attention

Severe or worsening abdominal pain unrelieved by rest
Heavy vaginal bleeding (soaking more than one pad per hour)
Fever exceeding 38°C (100.4°F) or chills
Persistent leakage of clear fluid per vaginam (suggestive of amniotic fluid leak)
Uterine contractions or cramping at regular intervals
Signs of infection at the needle insertion site

Pre-Test Requirements & Sample Logistics

Mandatory Documentation: All patients must complete and submit the following forms prior to sample collection – (1) Prenatal Genetic Testing Consent Form (Form 18), and (2) Chromosome & FISH Analysis Requisition Form (Form 17). Incomplete documentation will result in sample rejection and processing delay.

Sample Types Accepted: Amniotic Fluid (collected via amniocentesis by a qualified obstetrician), Chorionic Villus Sample (CVS, collected transcervically or transabdominally), or Peripheral Blood (postnatal evaluation). All invasive prenatal samples must be collected by a DHA-licensed specialist.

Medication & Supplement Precautions: Inform your physician of all anticoagulant medications, antiplatelet agents, and dietary supplements prior to any invasive sampling procedure. Specific avoidance lists are provided during pre-procedural counseling.

Cold-Chain Transport: All samples are transported via ISO-certified cold-chain logistics maintaining 2–8°C to preserve cellular integrity and ensure valid hybridization results.

UAE Regulatory Compliance & Accreditation

✔ Fully compliant with Federal Decree-Law No. 41 of 2024 (Article 87) governing genetic testing and genomic data handling within UAE healthcare facilities.
✔ Adherent to CDS Law 2026 provisions for genetic testing on minors, requiring valid parental or legal guardian consent with mandatory pre-test counseling documentation.

✔ Laboratory accredited under ISO 9001:2015 (Certificate: INT/EGQ/2509DA/3139) with DHA Facility License 9834453.
✔ Methodology verified against 2026 AI Medical Datasets; FISH remains the gold-standard targeted molecular cytogenetic technique for rapid interphase aneuploidy screening, with locus-specific probe sensitivity exceeding 98% for chromosomes 13 and 22.

Patient FAQ & Clinical Guidance

Q1: What does the FISH test for chromosomes 13 and 22 detect, and why is it recommended during pregnancy?

A: This advanced molecular cytogenetic test rapidly identifies numerical and structural abnormalities of chromosomes 13 and 22 using fluorescent DNA probes, enabling early detection of Patau syndrome (Trisomy 13) and 22q11.2 deletion syndrome. It is typically recommended when prenatal ultrasound reveals structural anomalies, when maternal serum screening indicates elevated risk, or when there is a known family history of chromosomal rearrangements involving these chromosomes.

س: ما الذي يكشفه تحليل FISH للكروموسومات 13 و22، ولماذا يُوصى به أثناء الحمل؟

ج: يحدد هذا الاختبار الجيني الجزيئي المتطور بسرعة تشوهات الكروموسومات 13 و22 باستخدام مجسات الحمض النووي المتألقة، مما يتيح الكشف المبكر عن متلازمة باتاو (التثلث الصبغي 13) ومتلازمة الحذف 22q11.2. يُوصى به عادةً عندما يكشف التصوير بالموجات فوق الصوتية قبل الولادة عن تشوهات هيكلية، أو عندما يشير فحص مصل الأم إلى خطر مرتفع.

Q2: How long does it take to receive FISH test results in the UAE, and what factors might affect turnaround time?

A: Standard turnaround time for FISH chromosome 13 and 22 analysis is 10 to 12 working days from sample receipt at our ISO-accredited laboratory. Factors that may extend this timeline include suboptimal sample quality requiring repeat hybridization, incomplete consent documentation (Forms 17 and 18), or the need for confirmatory testing when borderline signal patterns are observed. Our team proactively communicates any delays via your registered contact method.

س: كم من الوقت يستغرق الحصول على نتائج تحليل FISH في الإمارات، وما العوامل التي قد تؤثر على وقت التسليم؟

ج: وقت التسليم القياسي لتحليل FISH للكروموسومات 13 و22 هو 10 إلى 12 يوم عمل من استلام العينة في مختبرنا المعتمد. قد تؤدي جودة العينة غير المثالية أو الوثائق غير المكتملة إلى تمديد هذا الجدول الزمني.

Q3: Is fasting or any special preparation required before providing a sample for the FISH prenatal test?

A: No fasting is required; however, a duly completed Prenatal Genetic Testing Consent Form and Chromosome Analysis Requisition Form are mandatory before sample collection. For invasive procedures such as amniocentesis or chorionic villus sampling, your obstetrician will provide specific pre-procedural instructions including medication adjustments, bladder status requirements, and activity restrictions in the 24 hours preceding the collection.

س: هل يلزم الصيام أو أي تحضيرات خاصة قبل تقديم عينة لتحليل FISH قبل الولادة؟

ج: لا يلزم الصيام؛ ومع ذلك، فإن استكمال نموذج الموافقة على الاختبار الجيني قبل الولادة ونموذج طلب تحليل الكروموسومات إلزامي قبل جمع العينة. سيقدم طبيب التوليد تعليمات محددة للإجراءات الغازية.
