Overview
Aneuploidy is a genetic disorder where the total number of chromosomes are greater or lower than the usual number (46). Trisomy is a type of aneuploidy where there is an additional chromosome in the body, whereas monosomy is another type of aneuploidy where the body is missing a chromosome copy, i.e., has only 45 chromosomes. Examining for copies and abnormalities in chromosomes in the amniotic fluid can help detect genetic disorders. The Trisomy (Aneuploidy) FISH test is conducted to detect abnormalities in chromosomes 13, 18, 21, X, and Y using Fluorescence In Situ Hybridization. This diagnostic test is specifically designed to identify aneuploidies, which refer to the presence of an abnormal number of chromosomes. To ensure accurate analysis, it is essential to provide a detailed clinical history, including the anomaly scan report, along with the sample. Furthermore, a consent form in compliance with the guidelines of the Pre-Conception and Pre-Natal Diagnostic Techniques (PCPNDT) must be duly signed and submitted. The Trisomy FISH test plays a crucial role in prenatal screening and diagnosis, enabling healthcare professionals to identify and inform expectant parents about chromosomal abnormalities such as Down syndrome (Trisomy 21), Edwards syndrome (Trisomy 18), Patau syndrome (Trisomy 13), and other related conditions.

Frequently Asked Questions
This test detects the presence or absence of abnormal numbers of chromosomes 13, 18, 21, X, and Y in your genetic material.
• Detect genetic conditions like Down syndrome (trisomy 21), Edwards syndrome (trisomy 18), and Patau syndrome (trisomy 13) • Diagnose sex chromosome abnormalities and aneuploidies like Turner syndrome (monosomy X) and Klinefelter syndrome (XXY) • Assess the risk of certain genetic conditions during pregnancy • Provide valuable information for prenatal counselling and decision-making
This test is recommended when • A pregnant woman wants to assess the risk of genetic abnormalities in the fetus. • A person exhibits physical or developmental abnormalities suggestive of a chromosomal disorder. • There is a family history of genetic disorders or a previous child with a chromosomal abnormality.
Abnormal results may indicate the presence of conditions like Down syndrome, Edwards syndrome, Patau syndrome, or sex chromosome aneuploidies. However, abnormal results do not provide a definitive diagnosis and should be discussed with your doctor. Further diagnostic tests like genetic counselling, karyotyping, or microarray testing may be recommended.
A small amount of amniotic fluid will be collected during a procedure called amniocentesis. The sample will be sent to the laboratory for analysis.
• A detailed clinical history, including an anomaly scan report, must be submitted along with the sample. • A duly signed consent form as per PCPNDT guidelines must be provided. • Follow any instructions provided by your doctor regarding eating and drinking before the procedure. Please reach out to your healthcare provider for any specific requirements.
Other tests that may be ordered alongside the Trisomy (Aneuploidy) Chromosome 13, 18, 21, X,Y by FISH test include: • Detailed ultrasound to assess fetal anatomy • Maternal serum screening tests to assess the risk of chromosomal abnormalities • Genetic counselling to discuss the implications and options based on test results
Down syndrome screening, trisomy screening, aneuploidy testing
Down syndrome is a genetic disorder caused by the presence of an extra copy of chromosome 21. It leads to physical and intellectual disabilities, distinctive facial features, and an increased risk of certain health conditions such as heart defects and thyroid problems.
