About Premaitha Health plc

Premaitha Health (AIM: NIPT) is an innovative molecular diagnostics company employing the latest advances in DNA analysis technology to develop tests for non-invasive prenatal screening (NIPT) and other applications. Premaitha's flagship product, the IONA® test is the first non-invasive in vitro diagnostic CE marked product for prenatal screening enabling clinical laboratories to offer a regulated NIPT in-house.

The IONA® test estimates the risk of a fetus having Down's syndrome or other serious genetic diseases. The IONA® test has a higher detection rate and lower false positive rate than existing screening tests, giving pregnant women, their families and their doctors greater confidence in the result and reducing the need for unnecessary invasive follow-up tests and the associated anxiety and stress.

The IONA® test is a complete diagnostic system that is simple and standardised, enabling Premaitha's clinical laboratory customers to perform the test in their own facilities. This supports Premaitha's strategy of accelerating the broad dissemination of NIPT tests to ensure that their benefits are available to pregnant women everywhere.  

Premaitha is listed on the AIM market of the London Stock Exchange. Premaitha is ISO 13485 certified and its R&D, manufacturing and commercial operation is located at Manchester Science Park, UK.
