Why perform miscarriage testing?

The results obtained from testing can reduce a patient's emotional burden, and information from the results can improve the chances of a future successful pregnancy. If the cause of the loss is determined to be due to a chromosome abnormality in the fetus, parents can usually be reassured that the chance of recurrence is low, and avoid a costly medical work-up.

What conditions can Anora detect?

  • Trisomy—extra or missing chromosomes (e.g., Trisomy 21 (Down syndrome), Trisomy 13 (Patau syndrome), Trisomy 18 (Edward syndrome))
  • Triploidy—a complete extra set of chromosomes
  • Deletions and duplications—extra or missing pieces of a chromosome
  • Uniparental disomy (UPD)—two copies of a chromosome from the same parent with no copies from the other parent
