Plan your test

Sample
Amniotic fluid or chorionic villus sample (CVS). Confirm specific sample type requirements with the laboratory before collection.
Results
Confirm with the laboratory before booking.
Preparation
No specific patient preparation is required for the sample collection itself (amniocentesis or CVS). However, these procedures are invasive and require consultation with a healthcare provider.

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 indicates increased risk for Trisomy 18.
  • ✓Advanced maternal age (typically over 35).
  • ✓Abnormal findings on ultrasound.
  • ✓Previous pregnancy affected by Trisomy 18.
  • ✓Family history of chromosomal abnormalities.
  • ✓Confirmation of suspected Trisomy 18 from other screening tests.

In plain language

What this test helps you understand

This test is used for the prenatal diagnosis of Trisomy 18 (Edward syndrome) by detecting an extra copy of chromosome 18 in fetal cells. It helps provide timely information for pregnancy management and counseling.
The FISH Trisomy 18 Edward Syndrome Test is a specialized genetic test used during pregnancy to detect Trisomy 18, also known as Edward syndrome. This condition occurs when a fetus has an extra copy of chromosome 18, which can lead to significant health challenges. This test utilizes Fluorescence In Situ Hybridization (FISH) technology to analyze fetal cells for the presence of this chromosomal abnormality. Early detection provides crucial information for expectant parents and their healthcare team to make informed decisions about pregnancy management and prepare for potential outcomes. The test offers a relatively rapid way to identify this specific genetic condition compared to other cytogenetic methods.
