Information on the interpretation of Ct-values in case of positive test results
A Ct value >34 probably excludes contagiosness under the following conditions:

• no more clinical symptoms are present
• there has been no recent contact with a COVID-19 PCR positive person
• the sampling has been performed correctly
• and/or if the patient was tested PCR positive more than 10 days ago.

Please note that a low viral load may also be present in the early stage of infection before any clinical symptom is apparent! In case of a primary positive test, the patient must follow the classic quarantine regardless of the Ct value.

Ct values should therefore be interpreted with caution and only by the physician who can confront the PCR results with anamnesis, clinical findings, previous PCR results (if available) and other lab test results.

The analytical techniques of RT-PCR gives a numerical result called Ct (cycle threshold), which approximately estimates the viral load (the Ct being theoretically inversely proportional to the viral load).

A Ct value above 37 is considered as negative result.
