A little something that might be of interest...
I recently received a letter from Ipsos Mori asking me to take part in a COVID-19 in-home antibody testing research study.
The home-test kit arrived Monday, and I took the test Wednesday. Disappointingly - though perhaps unsurprisingly - I tested negative for antibodies. After taking the test, I had to fill in a long questionaire covering subjects such as my behaviour during lockdown.
[Proviso: The literature that came with the test repeatedly points out that the test is not reliable at an individual level. The purpose of the study is to estimate how many people have been infected with COVID-19.]
