I have been a participant in UK biobank for many years now and have just received an invitation to join their Covid Antibody study which I have agreed to. Is a simple finger prick test done at home and then you report the results on line. As someone with ET who has had Covid and also my first jab I will be very interested to see my results. I know antibodies are not the whole picture when looking at Covid protection but will be interesting. I will let you know what my results are when I do the test
Janet, dx ET triple negative
