We also have a series of questions to answer each time we do the test. My Wife also does a lateral flow test twice a week for work requirements and I occasionally do a lateral flow about a week after family gatherings. Neither of us has tested positive in all that time.Seminole wrote: ↑Sat Aug 28, 2021 7:17 pm Ive only been around antibody blood tests that differentiate between natural infection antibodies and those after vaccination being used to tell if you've been previously infected not to test vaccine efficacy drop via waning antibody counts
Presumably you are in a research group?
The antibody testing has been a blood test once a month since April and we've shown positive for antibodies every time.
The data showing a drop off in antibodies comes from an Israeli study.
Just to be clear on this the antibody tests you are having are specifically for antibody types produced by vaccination and not through infection? and if so have you ever been tested for natural infection antibodies?.
The Israeli study is worrying but Its my understanding its largely extrapolated from case data rather than antibody testing so is open to being slewed by many factors
Have to say twice weekly Lateral flow testing for hospital staff not a great deal more than window dressing, but can understand why they don't go further
