A proposed regulatory shift has injected uncertainty into the laboratory-testing market just as startups advance various tests to detect diseases sooner and personalize treatments.
Startups seizing advances in fields such as genomics and artificial intelligence are designing laboratory-developed tests to spot cancer and other illnesses before symptoms arise and to identify optimal therapies.
Lab-developed tests are created and carried out in a single lab.
Labs perform these tests on blood or other specimens shipped to them. Most genetic tests, for example, are lab-developed tests.
The FDA says it historically has exercised its discretion not to regulate such tests, thus allowing startups to introduce the tests quickly and at relatively low cost.
