QIAGEN N.V. has announced the U.S. regulatory approval of PartoSure, which is a novel test for assessing the risk of spontaneous preterm birth in patients with symptoms of preterm labour. The pre-market approval of PartoSure by the FDA follows successful uptake of the rapid, accurate test in more than 35 countries across Europe, the Middle East, Asia and Latin America.
