01

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.

  • ✓Advanced maternal age (35 years or older)
  • ✓Abnormal prenatal screening results
  • ✓Family history of chromosomal abnormalities
  • ✓Previous child with a chromosomal abnormality
  • ✓Abnormal ultrasound findings
  • ✓Prenatal assessment of fetal sex

In plain language

What this test helps you understand

This test helps identify the presence of Trisomy 18 (Edwards syndrome) and the sex of the fetus (presence of Y chromosome) during pregnancy, aiding in prenatal diagnosis and management.
The FISH Amnio Three Probes Trisomy 18 X Y Test is a specialized prenatal diagnostic test used to identify specific chromosomal abnormalities in a fetus. This test utilizes Fluorescence In Situ Hybridization (FISH) technology to analyze cells from an amniotic fluid sample. It specifically looks for the presence of an extra copy of chromosome 18 (Trisomy 18, also known as Edwards syndrome) and determines the presence of the Y chromosome, which indicates the sex of the fetus.

This test is typically performed during pregnancy to provide expectant parents and healthcare providers with crucial information about the baby's genetic makeup. Early detection of conditions like Trisomy 18 allows for informed decision-making regarding pregnancy management and preparation for potential medical needs after birth.

Who might consider this test? Expectant mothers who may benefit from this testing include those aged 35 and older, individuals with a family history of genetic disorders, those who have received abnormal results from previous prenatal screenings or ultrasounds, or those who have previously had a child affected by chromosomal abnormalities. Discuss your specific situation with your healthcare provider to determine if this test is appropriate for you.

Questions people ask

Frequently asked questions

FISH (Fluorescence In Situ Hybridization) is a laboratory technique that uses fluorescent probes to detect specific DNA sequences on chromosomes. It allows for the visualization of specific genetic material.
Trisomy 18, also known as Edwards syndrome, is a genetic condition caused by the presence of an extra copy of chromosome 18. It can lead to significant health problems and developmental delays.
This test is performed on an amniotic fluid sample, which is typically collected via amniocentesis after 15 weeks of gestation.
The sample is collected through a procedure called amniocentesis, where a small amount of amniotic fluid is withdrawn from the uterus using a needle. This procedure is performed by a trained healthcare professional.
A duly filled Prenatal Genetic Testing Consent Form (Form 18) and a Chromosome & FISH Analysis Requisition Form (Form 17) are mandatory.
The sample should be shipped at a temperature of 18-22°C and must not be frozen. Please confirm specific transport requirements with the laboratory before sending the sample.
