We collect your data directly from you via our website.

What personal data do we process ?

We remind you that personal data is information relating to an identified or identifiable natural person (the “data subject”), such as your first and last name, postal address or health data.

The categories of personal data we process are as follows:

treatment activity

shelf life (active base)

legitimate interest

identification data, connection data and logs, data relating to the management of contracts, appointments and newsletters

As part of the French law on healthcare reform of December 17, 2010, which provides for the introduction of a platform for sharing and exchanging medical data between healthcare professionals involved in your care, the results of your examinations will be transmitted to the Agence E-Santé and recorded in your personal medical record (DSP).

You may object to the transmission of your health data to Agence E-Santé as part of the PHR. You can notify us of your objection either directly at one of our collection centers or by sending us a written message.

You can exercise this right at any subsequent request.

As part of our services, we systematically send short messages (SMS) as soon as the results of analyses concerning your file are available. The purpose of this communication is to keep you informed as quickly as possible of the availability of this important information, and to offer you the option of subscribing to our patient results server if no account is associated with the mobile phone number in question.

By accepting this SMS notification service, you expressly consent to receive these communications for the receipt of test results.

If you wish to change or object to this method of communication, please click on the unsubscribe link in the SMS or contact us to update your notification preferences.

Who can access your personal data?

Your data will be communicated, if necessary, only to the following recipients:

  • Authorized Ketterthill personnel;
  • Subcontractors and trusted service providers, particularly in charge of IT.

We make every effort to ensure that the number of such persons remains as small as possible.

We only provide our trusted service providers with the information they strictly need to provide the service and they may not use your personal data for any other purpose.

We always make our best efforts to ensure that all our trusted service providers with whom we work maintain the security of your data.

We also ensure that when our relationship with a trusted service provider comes to an end, the service provider deletes your personal data without delay.

We select our trusted service providers with great care, ensuring that they offer sufficient guarantees, particularly in terms of expertise, reliability and resources, to implement technical and organizational measures capable of meeting the requirements of applicable legislation, particularly in terms of security. In this respect, we ensure that our trusted service providers process personal data only on our documented instructions. We also ensure that their staff have undertaken to respect confidentiality or are subject to an appropriate legal obligation of confidentiality.

What are your rights as a data subject?

You have the right to access, rectify, delete and port your personal data, as well as the right to limit the processing of such data.
