This plugin hasn’t been tested with the latest 3 major releases of WordPress. It may no longer be maintained or supported and may have compatibility issues when used with more recent versions of WordPress.

Corona Test Results


Management of Corona/COVID-19 test results with online check for the patients/citizens. Make the quick smear test procedure easier for both yourself and the person being tested and transmit the test result (positive/negative) via online query. Regardless of whether you’re a family doctor’s practice, municipal testing center, pharmacy, laboratory, …

🦠 For medical practices, test centers and laboratories: Generate random codes and print out an information sheet with a URL and QR code for online querying of results, as well as a document for linking the code and the fixed result at the test location.
🦠 Reduced conversation effort: (Premium) Individual information and recommendations for action can be displayed for each status page (result pending/positive/negative). This significantly reduces conversation times with patients/citizens. In this way, information can be read at home without stress.
🦠 No endless attempts to reach test subjects by phone: There is no need to contact test subjects by telephone to report the test results.
🦠 Data protection included: Personal data is not stored on the server if the certificate generation feature is not activated or no certificate is requested. Otherwise, all personal data is stored encrypted.

Intuitive operation, great time savings, comfort for patients/citizens. No queues with an increased risk of infection and no confusion when communicating the results. The patient / citizen is assigned to the smear test result using a unique code.


  • Generation of unique random codes for assigning and retrieving test results
  • Generation of document for the testing location and the test subjects
  • QR code for easy access to the test result by the patient/citizen
  • No storage of sensitive data on the server when certificate functionality is not used


  • Individually adaptable to the design of the website
  • Custom content on the different result pages (e.g. for further information and instructions)
  • Customizable texts and settings if needed
  • Batch generation of codes and documents
  • CSV export of codes
  • Generation of test certificates that can be printed or sent by email (contact us for a template customization offer)
  • Scanning of vCard data from a QR code in the test registration form (e.g. provided by our Quick Check-In feature or some official contact tracing apps like “Corona-Warn-App” used in Germany) ¹ ²
  • Import personal data from appointment booking tools/plugins upon test regitration ¹ ³
  • Quick Check-In: Print out a poster to lead about-to-be tested persons to a page where they can create a QR code containing their personal data while waiting, to further speed up the registration process
  • (Data transfer: Send test results to official contact tracing apps) ⁴
  • Label printing for easier assignation of test kits and results

Important: If you are using any caching plugin, make sure that the page containing the result retrieval form is added as an exception so it is never being cached, as this will otherwise lead to the form no longer working once the security nonce expires.

¹ access via HTTPS protocol required
² webcam or compatible scanning device required
³ currently supported: Bookly plugin (Bookly Pro is required to make use of additional fields for address and birth date)
⁴ currently supported: (Corona-Warn-App (Germany) (requires PHP >=7.3.0))

For reasons incomprehensible to us, despite working functionality and already having successfully connected users, T-Systems is currently refusing further integrations when using our plug-in. We will try to clarify this issue, but for the time being we can only advise you to manually use the alternative Corona-Warn-App portal solution in addition to our plug-in.

FEATURE IDEAS (become a sponsor for prioritized implementation)

Does Corona Test Results respect data privacy?

Yes, it does! If you’re not using the certificate generation feature, or a tested person does not request a certificate, private data will not be stored on the server at all.
Private data needed for certificate generation is stored in encrypted form. But please check what additional data privacy regulations and requirements might apply in your area.

Is this system tested and being actively used?

Yes, it is approved by regular use in a family doctor’s practice that we’re in contact with, as well as several testing locations located in Germany and around the world.

Isn’t it too much effort?

To the contrary, it saves a lot of time for the testing personnel!

How does the testing process work with the plug-in?

There are different ways how you can use the plugin. Currently it is designed for the following workflow:
1. Create code: You generate a unique code via “Register test” and enter the data (full name and date of birth) of the person being tested.
2. Generate PDF: You print out the provided PDF, which consists of two A5 pages. One part is given to the tested person, the other part is processed at the test site.
3. Corona test: Once the test has been completed and the result is known, use “Assign result” to assign the test result to the code registered.
4. Test result: The person tested gets to the results page via the code on their printout (manual entry or via QR code) and can read the result.
5. Attestation/Certificate: Upon request, the person tested will receive a certificate of the test result by email.

With the premium version, additional information such as instructions can be offered on the results pages (pending/positive/negative).

Does ist come with an integrated booking system?

While there is no integrated booking functionality, you’re able to read bookings from the third-party plugin called “Bookly” and copy the data over to the registration form. Mind though that we have no control over how Bookly handles the user data and you may need Bookly Pro and additional Bookly Add-Ons to make use of specific features.

Does the plugin create a certificate about the test result?

Yes, as of version 1.4.0 of the plug-in, certificates can be generated when assigning the test results, which can then either be printed out or sent by e-mail.

Will my external Camera / QR Scanner work with the plugin?

Any device that is detected as a camera in the web browser should work. Please check if your device is recognized as a camera on this page, which is a demo of the library that we use for QR code scanning:

We try to also support scanning devices that are detected as a keyboard by the operating system. Simply scan the code while the registration form is open and the browser window or tab is focused. This implementation is currently experimental and we’re looking forward to your feedback.
Starting with version 1.10.2, we successfully tested this input method with a Tera HW0002 handheld scanner. (Set the data format to Unicode/UTF-8 and the keyboard language to “International Keyboard”, or “ALT method” for some devices)
USB connection is recommended for fastest and reliable scan results. 2.4G also works, but Bluetooth seems to be quite unreliable and should be avoided.

Keeping track of and having to enter PINs for each test upon certificate generation is quite time-consuming – is it really necessary?

The PIN, which is not stored in the system and should therefore only be available offline in printed form, is an additional security measure to protect the patient data. This is a trade-off between data protection and using an open, online system like WordPress instead of a local software solution.

Mit dem Tool kann mein Kunde jetzt die Corona-Testergebnisse in seiner Station sehr einfach verarbeite. Für einen Support antwortet der Entwickler schnell und Kompetent. Mich würde noch die automatische Anbindung an das Meldesystem ans Gesundheitsamt freuen, dann würde ich auch einen sechsten Stern vergeben 🙂 … kann man aber auch gut so machen, wäre halt noch bequemer.

Dank diesem Tool können wir die Corona Testergebnisse sehr einfach teilen. Die Bedienung ist super einfach! Bei Problemen antwortet der Entwickler sehr schnell. Ich würde mir wünschen, das mehr Testzentren das Plugin einsetzen. Es ist 100% auf deutsch!
