For Participants


Finger-prick blood collection

We are asking CSS Biobank participants to provide us with a self-collected blood sample. This involves pricking your finger and squeezing drops of blood into a little tube, and can be done from home.

The instruction sheet is available here.

A video demonstrating how to complete this kind of blood collection is available here. Please note this video was created by the supplier. We will only use your blood for COVID-19 research.

Stool collection

We are asking some CSS Biobank participants to provide us with a stool (faeces) sample. This can be done from home.

The instruction sheet is available here.

A video explaining how to complete this stool collection is available here.
