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
