Invitae Pregnancy Loss Chromosomal Microarray Analysis for FFPE
Test description
Pregnancy loss chromosomal microarray analysis (CMA) analyzes products of conception (POC) tissue to determine whether a miscarriage, an intrauterine fetal demise (IUFD), or a stillbirth was caused by a chromosome abnormality.
- Analyzes products of conception (POC) tissue that has been preserved in a formalin-fixed, paraffin-embedded (FFPE) block
- Turnaround time is 10-12 days on average
- Microarray analysis detects:
- Whole and segmental aneuploidies
- Submicroscopic gains and losses that cannot be detected using karyotype
- Size and gene content of copy number variations (CNVs)
- Regions of homozygosity, which may suggest shared ancestry and an increased risk for autosomal recessive disorders
- Uniparental isodisomy, which can indicate a risk for an imprinting disorder
- Triploidy and complete molar pregnancies
- Simultaneously detects maternal cell contamination (MCC) without a maternal blood sample
- Allows for appropriate medical management and recurrence risk counseling
