I know some nurse who works for a private hospitals (Philippines), and I found out that there are some inconsistency on the process. Some of these hospitals, offer Free test but some they don't. However, the Free has only inclusions and limited only some test (not a fully COVID-19 standard test). Once, confirmed these private hospitals will transfer the patient to a Government Hospital and a signed waiver is included with it (Typical medical practice of a hospital, I guess).
They need to improve their testing and make sure its accurate, otherwise, the report shown would be understated and there is a big risk that there are people who are already infected but are still free going in public places, this way the disease will spread easily and the more people will panic.
