Test Overview & Methodology
The Chromosome 21 FISH test rapidly detects trisomy 21 (Down syndrome) in prenatal samples such as amniotic fluid, chorionic villi, or cord blood, and monitors hyperdiploidy in oncology specimens. Methodology: Fluorescence In‑Situ Hybridization (FISH) — targeted DNA probes for chromosome 21 enumeration. Turnaround Time: 3–4 working days.

Physician Insight & Safety Protocols
“I understand the emotional weight of prenatal genetic testing. A positive result requires correlation with ultrasound findings and comprehensive genetic counselling. Please consult your doctor before making any clinical decisions.”

Advisory: Medication and Clinical Safety
⚠️ Do not discontinue any prescribed medication without consulting your doctor. If you experience heavy bleeding, fever, leakage of amniotic fluid, or severe pain after sample collection, seek emergency care immediately.
Exclusion Criteria & Emergency Red Flags
- Active vaginal bleeding or ruptured membranes before scheduled amniocentesis.
- Known allergy to ultrasound gel or local anaesthetic used during collection.

- If you experience heavy bleeding, fever, leakage of amniotic fluid, or severe pain after sample collection, seek emergency care immediately.
Patient FAQ & Clinical Guidance
1. What is the Chromosome 21 FISH test used for?
This FISH-based test detects an extra chromosome 21, confirming Down syndrome diagnosis with 99.9% sensitivity in 3-4 days. It is the gold‑standard rapid prenatal screening tool and is also used in oncology to monitor hyperdiploidy in haematologic malignancies.
2. How is the sample collected?
Sample collection must be performed in an accredited hospital setting (e.g., amniocentesis, chorionic villus sampling). Our DHA-licensed team coordinates with your hospital. No home phlebotomy is available for this invasive procedure.
3. Do I need a doctor’s prescription?
Yes, a doctor’s prescription is mandatory for prenatal genetic testing. Exemptions apply for pregnancy monitoring, surgical clearance, or travel purposes. Contact us on WhatsApp for verification.
4. What is the turnaround time?
Results are typically available within 3–4 working days from sample receipt in the laboratory.
