Under a proposed decision, to be finalized in August and become effective in late 2020, NIPT would only be covered for women with particular fetal trisomy risks.
Last week, Invitae launched its Non-Invasive Prenatal Screening test while Myriad expanded its Prequel Prenatal Screen to cover all aneuploidies.
The company, which changed its name from Premaitha Health last month, saw a 73 percent increase in testing volumes during the first half of fiscal year 2018.
During the first year of the TRIDENT-2 study, 74,000 women opted for NIPT, which was switched from in-house-developed platforms to Illumina's VeriSeq in May of this year.
By early 2020, the UK company plans to develop a version of its Iona test that uses Illumina's sequencing technology.
Although the two studies seem to provide conflicting results on the impact of PGS, the "devil's in the details," according to an outside expert.
The report states that using NIPD for trisomy 21 in high-risk women could "probably reduce" the total number of invasive tests though the data is incomplete.
The company plans to launch the system this summer in Europe, aiming to broaden cell-free DNA screening for trisomy 21, 18, and 13.
The suit alleges that Natera's Panorama test infringes US Patent No. 9,493,831 patent, which covers sequencing library preparation methods applied to maternal blood samples.
The company is now seeking commercial partners in Brazil to make the Iona test available in the country.
