Genetic testing provides answers
Invitae’s chromosomal microarray analysis (CMA) for pregnancy loss is DNA-based and delivers results in more than 92.4%1 of cases in as soon as 10-12 days, on average. No cell culture is required.
Uncover the cause of recurrent miscarriage
Approximately one in five clinically recognized pregnancies ends in miscarriage. Of first-trimester pregnancy losses, more than 50% are due to a fetal chromosomal abnormality.
Find answers about an intrauterine fetal demise (IUFD) or stillbirth
Invitae testing can help determine the cause of second and third-trimester loss to give patients answers to their hardest question: why.
Benefits of microarray testing
-
Better suited for the analysis of pregnancy loss tissue
-
Can be performed on formalin-fixed, paraffin-embedded samples
-
No cell culture required
-
Simultaneously detects maternal cell contamination without a maternal blood sample
-
Readily detects triploidy and molar pregnancies
-
Covers more bases to help prevent unnecessary testing
-
Allows for appropriate medical management and recurrence risk counseling
Microarray vs. karyotyping
| Invitae’s microarray | Karyotyping | |
| Percentage of cases where results are obtained | >92.4%1 | 60-80%1-3 |
| Cell culture required | No (DNA-based) | Yes (frequent cell culture failure) |
| Can be performed on formalin-fixed, paraffin-embedded samples? | Yes | No |
| Detects submicroscopic gains and losses | Yes | No |
| Detects submicroscopic imbalances and molar pregnancy | Yes | No |
| Detects maternal cell contamination | Yes | No |
| Turnaround time | 10-12 days on average | ≥2 weeks (if culture is successful) |

Additional tests for patients across all reproductive stages
Invitae offers a comprehensive test menu that delivers actionable insights for all your patients, whether they are considering pregnancy or already pregnant.
Proactive cancer screening
More than 9% of healthy adults have a genetic risk of developing cancer.
Cancer screening can offer healthy adults an opportunity to understand their DNA, assess heritable cancer risk, and take proactive action if necessary.
Carrier screening
80% of children born with genetic disorders have no family history.
The American College of Obstetricians and Gynecologists (ACOG) recommends offering carrier screening to all patients of reproductive age, either before or during pregnancy.
Non-invasive prenatal screening (NIPS)
Invitae NIPS can be performed as early as 10 weeks gestational age.
Invitae NIPS offers an industry-leading low test failure rate of <0.1% and offers 99% sensitivity and specificity for most chromosomes screened.
