Whether further examinations are carried out after a positive coronavirus test result depends on how the illness progresses.

In mild cases with minimal symptoms it is often sufficient to stay at home, rest and avoid all social contact. No further examinations are necessary.

If the illness is moderate or severe, respiratory distress and fever can occur. In that case, additional blood and urine samples are taken so that other illnesses, e.g. flu or bacterial infections, can be excluded.

As the illness proceeds, further blood samples may need to be taken to check on kidney and liver function, for example.

Imaging procedures may also be used, such as X-rays of the chest and abdominal cavity and CT (computer tomography) scans of the lungs. 

Further information about diagnostic procedures is available from the Robert Koch Institute.
