Clark, yes we do it ourselves. I know that the team visited China to learn about the new virus and to get samples. Then, government facilitated licencig procedure to get tests as soon as possible. It is PCR test, so we only needed samples and reagents, so we obtained samples and we produce reagents. And they also authorised several private commercial clinics to do testing and published the list of them, thus anyone may go and get tested for rather modest sum of about 2000 roubles, in case they want to know.
