Notes
Each participant of the Coronavirus Self-test Antibody Study received a self-administered lateral flow test through the post that was either a Fortress Fast COVID-19 Test or an AbC-19
TM Rapid Test. Fortress kits produced results that differentiated between IgG antibodies (long-term) and IgM antibodies (short-term). AbC-19
TM kits provided only positive test results for IgG antibodies.
Resource 4513 and Resource 4520 show the technical specifications of the Fortress and AbC-19 test kits.
