Start with fit

Is this the right test for you?

The best test starts with a clear clinical question. These are common reasons a clinician or family may consider this test.

  • ✓Prenatal screening for suspected chromosomal abnormalities
  • ✓Postnatal diagnosis of developmental delays or congenital anomalies
  • ✓Advanced maternal age (over 35)
  • ✓Family history of chromosomal disorders
  • ✓Abnormal results from other prenatal screening tests
  • ✓Previous pregnancy affected by chromosomal abnormalities

In plain language

What this test helps you understand

This test helps detect aneuploidy (an abnormal number of chromosomes) involving chromosomes 13 and 22. Identifying these abnormalities can provide crucial information for prenatal counseling, pregnancy management, and postnatal care.
The FISH (Fluorescence In Situ Hybridization) test for Chromosome 13 and 22 is a specialized diagnostic tool used during pregnancy (prenatal) or after birth (postnatal). It helps identify specific chromosomal abnormalities, such as having an extra copy of chromosome 13 (Trisomy 13) or chromosome 22 (Trisomy 22). These conditions can affect a baby's health and development. Early detection allows healthcare providers to offer appropriate guidance and support to families. This test is particularly relevant in cytogenetics and reproductive medicine.

SamplePrenatal: Amniotic fluid or Chorionic Villus Sample (CVS). Postnatal: Blood sample (usually collected in an EDTA tube). Confirm specific requirements with the laboratory before booking.
MethodologyFluorescence In Situ Hybridization (FISH). This technique uses fluorescent probes that bind to specific parts of the chromosomes, allowing visualization of their number and structure under a microscope.
PrivacyYour sample and report are handled confidentially. Ask the team how your information is stored and shared.
This test only detects abnormalities in chromosomes 13 and 22. It does not screen for other chromosomal abnormalities or genetic conditions. Results may be affected by sample quality. Confirm with the laboratory before booking.

Questions people ask

Frequently asked questions

FISH stands for Fluorescence In Situ Hybridization. It's a laboratory technique that uses fluorescent dyes to detect specific genetic material, like chromosomes, within cells.
Abnormalities in these chromosomes, such as Trisomy 13 or Trisomy 22, can lead to significant health issues. This test helps identify these specific conditions.
This test is typically recommended for individuals with specific risk factors or concerning findings from other tests. Discuss with your doctor if this test is appropriate for you.
Your doctor will discuss the results with you, explain what they mean, and recommend any necessary follow-up steps or consultations with specialists.
For prenatal testing, samples are collected via procedures like amniocentesis or CVS. For postnatal testing, a blood sample is usually taken. Your doctor will guide you on the collection process.
