Technologists were blinded to the identity of samples, and the order was randomized separately for each panel.
Symbols: +, positive; −, negative. The two symbols listed are the result of the first test/result of the second test.
Kappa measures the agreement beyond change, with 0.0 indicating no agreement and 1.0 indicating perfect agreement. For all kappa values, P < 0.001.
