I visited a medical institution, but I was diagnosed only with clinical symptoms without testing for the new coronavirus. Do you not carry out PCR tests?

As a result of a comprehensive judgment by a doctor, a person living with a person who has been confirmed to have a new coronavirus infection (family and cohabitants who share eating, drinking, bathing, going to bed, etc.) May be clinically diagnosed.
Even in that case, if it is necessary to administer a therapeutic drug such as oral drugs, the examination may be performed at the discretion of the doctor.
