Test Overview & Methodology
Fluorescence In-Situ Hybridization (FISH) for chromosomes 13 and the sex chromosomes (X and Y) is a rapid molecular cytogenetic assay that detects common aneuploidies including trisomy 13 (Patau syndrome) and sex chromosome anomalies (e.g., Turner syndrome, Klinefelter syndrome, Triple X, 47,XYY). The test delivers actionable results within 10–12 days from amniotic fluid, chorionic villus samples, or peripheral blood, enabling timely clinical decisions in prenatal and postnatal settings.
| Feature | Our FISH Test | Conventional Karyotyping |
|---|---|---|
| Precision & Sensitivity | 99.9% analytic sensitivity for targeted loci (13, X, Y) | ~99% but requires culturable cells; may miss low-level mosaicism |
| Methodology | Fluorescence In-Situ Hybridization (FISH) with locus-specific probes | G-banded karyotype; whole-genome analysis |
| Turnaround Time | 10–12 days | 14–21 days (culture-dependent) |
Physician Insight & Safety Protocols
“As a consultant medical geneticist, I emphasize that rapid FISH results must be integrated with detailed clinical history, ultrasound findings, and confirmatory karyotype when indicated. A normal FISH result does not exclude all chromosomal anomalies; comprehensive genetic counselling is essential before making irreversible clinical decisions.”

Medication Advisory
Do not discontinue any prescribed medication without consulting your doctor. This test does not replace ongoing clinical management or regular prenatal care.
Safety Exclusion Criteria & ER Red Flags
- Exclusion Criteria for Invasive Sampling: Active vaginal bleeding, unmanaged coagulopathy, acute maternal infection, placental abruption, allergy to local anaesthetics, or inability to give informed consent.
- Emergency Red Flags Post‑Procedure: Heavy bleeding, severe abdominal pain, fever >38°C, chills, foul-smelling vaginal discharge, leakage of fluid, or noticeable decrease in fetal movement. Seek immediate emergency care.
Patient FAQ & Clinical Guidance
1. What is the FISH test for trisomy 13 and sex chromosome aneuploidies, and why is it recommended during pregnancy?
Rapid FISH detection of trisomy 13 and sex chromosome aneuploidies from amniotic fluid or chorionic villus samples guides timely prenatal management. This test provides highly accurate results within 10–12 days, enabling early decision‑making when ultrasound or maternal serum screening suggests a high‑risk pregnancy.
2. How should I prepare for the test and what are the risks?
Before sampling, sign the prenatal genetic testing consent form (Form 18) and the chromosome and FISH analysis requisition form (Form 17). Invasive sampling (amniocentesis or chorionic villus sampling) carries a rare risk of miscarriage, bleeding, or infection; all procedures are performed under strict DHA‑licensed supervision to minimise complications.
3. How quickly will I get my FISH results and what do they mean?
Your FISH report is available within 10–12 days and will indicate the presence or absence of trisomy 13 and common sex chromosome aneuploidies. A normal result means no evidence of these targeted anomalies, but a full karyotype may still be recommended to exclude other structural chromosomal rearrangements. Consult your gynaecologist or genetic counsellor for complete interpretation.
