I have just done a Biosure antibody test as I was curious to see whether I had any after being double jabbed and having covid.
It has come back with a VERY faint line, but the kit says to count it as positive regardless of the strength.
Does anyone know if this is related to the level of antibodies or is it like a pg test where a line is a line? It took me a good ten minutes to get the tiny pinprick of blood needed for the test so I'm wondering if that might not have helped!
