The reference result was based on concurrent conventional test results and clinical adjudication. NA, not applicable.
Two targets were excluded because they did not have concurrent conventional test results.
All false-positive results had discrepant ME panel and conventional test results. None of the discrepant ME panel results were clinically adjudicated to represent true-positive results.
