Taking part in the PIENTER Corona Study

The 12th round of the study is in April/May 2024. Participants are asked to take a fingerprick blood sample using a self-sampling set and to fill in a questionnaire.

  • If possible, take the fingerprick blood sample and fill in the questionnaire on the same day. Send the collected blood to RIVM as soon as possible, preferably within 3 days.
  • Survey: Instructions have been emailed to you. Go to www.rivmportal.glean, enter your login details, and fill in the online questionnaire.
  • If you have not received the email, or if you prefer to fill in a questionnaire on paper, please send a message to
  • If you asked to fill in the questionnaire on paper, then a paper questionnaire will be sent to your home address. The paper questionnaire will be sent in a separate envelope and is not enclosed with the fingerprick self-sampling set.
  • Blood sampling: A general instruction video for collecting a fingerprick blood sample is provided on this website. The fingerprick blood sample instructions have been updated, and we now use a different collection tube. The tube containing the blood sample should be sent back to RIVM in the special envelope (inside the closed plastic bag).
