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)
✓Family history of chromosomal abnormalities
✓Previous pregnancy affected by genetic disorders
✓Abnormal prenatal screening results
✓Concerns about potential genetic conditions

In plain language

What this test helps you understand

This test helps identify potential chromosomal abnormalities (Trisomy 13 and 23) in a fetus, providing crucial information for prenatal management and decision-making.

The FISH for Pre or Postnatal Diagnosis Chromosome 13 23 test is a specialized genetic analysis used during pregnancy. It employs Fluorescence In Situ Hybridization (FISH) technology to identify specific chromosomal abnormalities, focusing on aneuploidy related to Trisomy 13 and 23. Understanding these conditions is important for expectant parents to make informed decisions about their pregnancy and prepare for potential health considerations. This test helps detect an abnormal number of chromosomes, specifically looking for extra copies of chromosome 13 or 23, which can lead to significant health issues in a newborn. Early detection allows for better management and planning during pregnancy. We have branches across Kenya, including Nairobi, Mombasa, and Kisumu, ready to assist you.

Questions people ask

Frequently asked questions

FISH (Fluorescence In Situ Hybridization) is a technique that uses fluorescent probes to detect specific DNA sequences on chromosomes.

Trisomy means having three copies of a chromosome instead of the usual two. Trisomy 13 and 23 are specific chromosomal conditions.

Yes, this test provides a definitive diagnosis for the specific chromosomal abnormalities it targets (Trisomy 13 and 23).

A qualified genetic counselor or medical professional will interpret the results and discuss their implications with you.

You will need to complete the Prenatal Genetic Testing Consent Form (Form 18) and the Chromosome & FISH Analysis Requisition Form (Form 17).
