They'll need to start with a whole new round, including clinical trials. My guess is that you're looking at a year minimal after all technical issues have been resolved ion the lab. RCE needs to first solve all technical issues to get a reliable test and that's no small task with multiple antigens to identify quantitatively. I'm not even sure they have already selected the final markers that will be targeted in the test. After that they'll need to select a company that will do the clinical test, doctors, patient criteria and selection, ethical committees to give permissions and much more. All takes careful planning and lots of time.
