FISH for Trisomy 13 & 21

Fluorescence in situ Hybridization, commonly known as the FISH test, is a genetic test employed to detect and map the genetic material in an individual's cells. This test can observe specific DNA features, including extra chromosomes, which indicate conditions like Trisomy 13 and 21.


  • Profile Name: FISH for Trisomy 13 & 21
  • Sample Type: Blood
  • Preparations Required: No specific instructions required before this test.
  • Report Time: 5 days

The Fish test for Trisomy 13 & 21, commonly called the Fish trisomy 13 & 21 test, is a pivotal prenatal diagnostic tool. Utilizing Fluorescence In Situ Hybridization, this molecular cytogenetic technique plays a crucial role in the early and accurate detection of chromosomal abnormalities, specifically targeting chromosomes 13 and 21. This test is particularly recommended for expectant parents over the age of 35 or those with a family history of genetic disorders. Its rapid results empower parents with essential information for informed decision-making, providing a comprehensive understanding of potential challenges associated with conditions such as Patau syndrome (Trisomy 13) and Down syndrome (Trisomy 21).

The Fish trisomy 13 & 21 test stands out for its targeted approach and reliability in prenatal genetic testing. Focusing on specific chromosomal regions enhances the precision of results, offering expectant parents valuable insights into their baby's genetic health. The test not only aids in risk assessment but also provides an opportunity for proactive and informed decision-making, ensuring that parents are well-prepared for any potential challenges associated with Trisomy 13 & 21.

Frequently Asked Questions

The FISH test is typically performed during pregnancy if initial screening tests suggest a high risk of Trisomy 13 or 21. It can also be performed after birth if the child displays symptoms characteristic of these conditions. However, the decision to conduct this test is often based on multiple factors, including family history, age, and other risk factors.

No special precautions are necessary for the FISH test. However, it's important to follow your healthcare provider's advice and instructions before and after any medical procedure to ensure optimal results and your overall well-being.

No, fasting is not required before a FISH test. You are allowed to consume food and drink normally prior to this diagnostic procedure.

The FISH test is vital in diagnosing Trisomy 13 and 21 because it facilitates early and accurate detection of these chromosomal abnormalities. Early diagnosis paves the way for appropriate interventions and effective management, thereby improving the affected individual's life quality and mitigating potential complications.

The FISH test provides vital information about the structure and number of chromosomes in the cells. It can determine if there is an extra copy of chromosome 13 or 21, which would indicate Trisomy 13 or 21, respectively. Additionally, the test can identify other chromosomal anomalies.
