Prenatal Testing
Reasons for Testing
Prenatal testing can give you reassurance and a better understanding of your pregnancy.
Reasons for testing may include:
• A family history of chromosome abnormalities
• Anomalies detected on ultrasound screening or maternal blood test.
• Advanced maternal age – over the age of 35 the risk of having a baby with a chromosomal abnormality increases.
• Anxiety
IGENZ offers two Prenatal Tests
• Cytogenetics prenatal
• FISH prenatal aneuscreen
Why have FISH & Cytogenetic Testing done together?
Both tests complement each other. FISH testing provides a quick screen for the most common chromosome numerical abnormalities. Cytogenetic testing detects structural and other numerical abnormalities that FISH cannot. Cytogenetic testing also confirms abnormalities detected by FISH.
