What if I change my mind after giving a blood sample?

You can contact us at childnc@ucl.ac.uk or 0800 092 1250.

Please note that when we asked if you would be willing to take part in this project we told you that any blood left over after the antibody test has been conducted may be stored for future research.  We can now confirm that this will NOT happen.  Any blood which is left over after the antibody test has been conducted will be destroyed by the laboratory.  None of your blood will be stored for future use.
