I recently recieved a letter asking if I wanted to take part in COVID-19 in home antibody testing research study - random people selected from a list of people who have a gp. So I went online to register and was one of the 'lucky ones'

to be accepted and got the kit yesterday. This morning I did the test which consists of a pinprick test with the blood going on a test strip and leaving for 10 -15 minutes for the result. It's not 100% accurate but I'm still okay about this as it may help.
My result is negative and I have completed the questionaire which involves general stuff such as what type of home I have, if I'm employed, unemployed etc. I clicked the disabled/long term ill for that and for other questions such as certain conditions - about 10 - so I was very good and clicked on depression, high blood pressure and anxiety. I've copied and pasted some links after I finished the questionaire as well.
The research is being done by the Imperial College London and Ipsos Mori on behalf of the Department of Health and Social Care
