Comparative study reveals microarray analysis yields higher genetic diagnosis rates than karyotyping in stillbirth cases, suggesting superior utility for nonviable tissue and congenital anomalies.
Microarray analysis is more likely than karyotype analysis to provide a genetic diagnosis, primarily because of its success with nonviable tissue, and is especially valuable in analyses of stillbirths with congenital anomalies or in cases in which karyotype results cannot be obtained.
