## Current Implementation
When a user is tested positive the CWA only displays "positive". Many patients ask where they can get more information like the cycle-threshold. We refer to our website where the user can get a pdf with everything on it.

## Suggested Enhancement
Implement a way that the lab can submit the ct-value.
These should include all 3 (or two) regions that are checked and the control values. (otherwise, the ct-value is useless)
I know this is a major change in the CWA-System :cry: 
### Example
| | ORF | nucleocapsid | spike S1 |
| ----- | ----- | ----- | ----- |
| Your Sample | 26.9 | 27.2 | 26.6 |
| Control 25 copys  / 500μL | 28.2 | 29.0 | 28.6 |
| Control 500 copys / 500μL | 23.0 | 22.1 | 22.8 |

## Expected Benefits
More information for the user and redundancy between lab-system and cwa.
Display more information for a positive result

@username_0 
Do you have a reference which explains what these values mean and what the person being tested can do with the information?

The ct (cycle-threshold) - value says (simplified) how many DNA replications cycles were needed to get a positive result. [1]
This gives an approximation how much virus was on the swab / in the patient.

The RKI has created a guideline [3] [4] on how to interpret the result in general and regarding the discharging of patients out of the isolation.  The most important part is, that a patient can be discharged after 10 days if there is a:
"positive PCR result only below a defined threshold value that allows a statement on the probability of cultivation (quantitative reference sample cell culture supernatant < 1,000,000 (10E6) copies/ml, for details see www.rki.de/covid-19-diagnostik)"

This could be very useful for patients that were tested positive, stayed for 2 weeks in isolation and are performing (e.g. for a travel/work) another PCR Test. This test may turn out positive but with ct-values that high that it doesn't really matter. 
Without this information, a patient can't contact his/her family doctor or the local health authority to get an explanation or even a "non-infectious certificate"

Hello community,

We have added this feature request to our internal Jira ticketing system. The developers are informed and will decide if and how the feature will be implemented together with the RKI. We will notify you about updates on the status of the feature requuest here on Gthub.

Regards,
CH
