What is Eluthia’s NIPT Extended?

Our NIPT Extended, the PreviaTest®, is currently the most extensive screening option for genetic aberrations. This test is currently only available at BGI (Health) in Hong Kong, one of the world’s largest supplier of genetic tests. We are proud to offer you this test exclusively in Germany.

More than 80 additional Microdeletion/ Microduplication Syndromes
Report of Incidental Findings

Additionally, incidental findings will be reported. In microdeletions / microduplications small pieces of a chromosome are missing or the same piece is found twice. Most microdeletions are very rare and the carriers of such microdeletions can have heterogenous phenotypes, depending on many factors. The most common microdeletion affects chromosome 22, the reason why it is called 22q11.2 Microdeletion Syndrome.  The incidence rate is around 1 in 4,000 births.

With PreviaTest you can screen for most deletions and microdeletions as well as duplications and microduplications (currently over 80). It is estimated that deletions, microdeletions, duplications and microduplications occur in about 1 in every 1,000 newborns and that the incidence rate does not depend on the mother’s age. Frequent microdeletion syndromes include:

Region Selection of relevant syndromes Prevalence (up to)

What about data security?

For transmission of patient data to another country it is essential to rule out a misuse of data. Therefore, the lab has been thoroughly audited. Multiple international validations and certificates (CLIA and ISO) as well as internal process guidelines prevent a misuse of data. Furthermore, the lab is subject to the European General Data Protection Regulation.

When can you expect the results?

The test results are usually available within 7 – 10 days.

Are there any test restrictions?

The test is only available for singleton pregnancies.

What are the possible results?

  • Low-risk result: low risk for your child to be affected by one of the screened syndromes.
  • High-risk result: heightened risk for your child to be affected by one of the screened syndromes.
  • No result: In very rare cases a result can not be generated because of various reasons. In these cases, please talk to your doctor about the further cause of action.

We express our recommendation of Ultrasound as an important part of prenatal care.

PreviaTest screens for fetal chromosomal aberrations. It complements the ultrasound of your physician and does not replace the ultrasound in any case.

Remember, it is always important to consult a qualified healthcare professional before taking any genetic test to make sure you fully understand the conditions being tested for. PreviaTest is a screening test: If the test result shows a high risk for a screened condition, it is recommended to have a diagnostic test for confirmation.

Please consider that non-invasive prenatal testing can be appropriate for you but at the same time unsuitable. Before having non-invasive prenatal testing, you should consult a qualified healthcare professional to make sure you fully understand all the relevant risks, diagnoses, therapy options and possible consequences and medical concerns.
