The Pregnancy Loss Pathway begins with IFISH for chromosomes 13, 15, 16, 18, 21, 22, X, and Y. If that result is normal, we recommend proceeding to chromosomal SNP microarray analysis, a service provided by the closely affiliated Clinical Cytogenomics Laboratory at the University of Washington. If the IFISH result is abnormal, we may recommend routine G-banded chromosome analysis. See our website for complete details about the Pregnancy Loss Pathway.
