Test Overview & Methodology
The Chromosomes 13 & 21 (FISH) analysis is a rapid, targeted prenatal genetic test that uses fluorescent DNA probes to count copies of chromosomes 13 and 21 in amniotic fluid, chorionic villi, or cord blood. It provides highly accurate aneuploidy screening for Patau syndrome (trisomy 13) and Down syndrome (trisomy 21) within 3–4 days, enabling timely clinical decisions.
| Feature | Our FISH Test | Alternative (Karyotype / Microarray) |
|---|---|---|
| Precision | >99% sensitivity for trisomies 13 & 21 | >99% but covers all chromosomes (broader) |
| Methodology | Fluorescence In‑Situ Hybridization (FISH) | G‑banded Karyotype / Chromosomal Microarray |
| Turnaround Time | 3–4 Days | 10–14 Days (Karyotype) / 5–7 Days (Microarray) |
Physician Insight & Safety Protocols
Dr. Lina Osama Zaki Quteineh (Consultant Medical Genetics, DHA Registration ID: 9294403) states:
“FISH analysis for chromosomes 13 and 21 provides an extremely reliable rapid screen for the most common aneuploidies; however, a negative FISH result does not completely exclude other chromosomal abnormalities. It is essential to correlate FISH findings with detailed ultrasound and maternal serum biomarker profiles. Confirmatory conventional karyotyping or chromosomal microarray is strongly recommended in cases involving structural anomalies or high pre-test probability. Always consult your referring physician for a comprehensive interpretation of your results.”
⚠ Medication Advisory
Do not discontinue any prescribed medication (e.g., anticoagulants, hormonal therapy) without consulting your doctor. This test does not replace clinical management; alteration of therapy may affect maternal or fetal health.
🚨 Exclusion Criteria & Urgent Red Flags
- Known maternal cell contamination (bloody tap) – may invalidate results.
- Amniotic fluid volume < 15 mL or sample not transported at 2–8°C within 24 hours.
- ER Warning : If you experience severe abdominal pain, vaginal bleeding, or fluid leakage after amniocentesis/CVS, seek emergency care immediately.
Patient FAQ & Clinical Guidance
1. What is the Chromosomes 13 & 21 (FISH) test used for?
This rapid FISH test detects trisomy 13 and 21 in prenatal samples, providing results within 3–4 days. It is primarily used during pregnancy to screen for Patau and Down syndromes when ultrasound or maternal serum screening indicates increased risk. Oncologists may also employ it to monitor acquired trisomies in certain hematological disorders.
2. What specimen types are accepted, and how is the collection performed?
Only hospital-extracted specimens are accepted for this analysis due to the invasive nature of the collection procedures. The accepted sample matrices are amniotic fluid (amniocentesis), chorionic villi (CVS), and cord blood. Collection is strictly performed within an accredited hospital facility by a qualified obstetrician or maternal-fetal medicine specialist.
3. Is a doctor’s prescription required for this test in Dubai?
A physician’s referral is generally required for cytogenetic testing. Our DHA-licensed team can verify clinical necessity through your referring physician. Please upload your referral form during the booking process or contact our support team via WhatsApp at +971 54 548 8731 for assistance.
