Microarray in Prenatal Medicine
Microarray is a technology that examines chromosomes for imbalances at a level of resolution that is significantly higher than traditional karyotyping. Just as karyotyping was revolutionary 30 years ago, microarray analysis is finding its place in prenatal testing.
Indications when a prenatal sample should be tested by microarray:
- Abnormal ultrasound findings
- Abnormal karyotype requiring molecular clarification
- Family history of known or suspected chromosome imbalances
- Previous pregnancy with multiple anomalies of unknown etiology
- History of multiple miscarriage or stillbirth of unknown cause
- Abnormal maternal serum screen
An assessment of Signature Genomics' experience of more than 30,000 pediatric and adult cases contributed to the development of these testing options available for prenatal cases. In addition, Board-certified genetic counselors are available to discuss your case with you at any time, even before the sample is sent to Signature Genomics.
