Sensitivity and specificity, Confusion matrix
false-positive rate = 1 - specificity(true negative/negative)
false-negative rate = 1 - sensitivity(true positive/positive)

positive percent agreement (new / non ref. std.) = 100% x 40/59 = 67.8%
negative percent agreement (new / non ref. std.) = 100% x 512/513 = 99.8%
overall percent agreement = 100% x (40+512)/572 = 96.5%
CDC: Requirement for Proof of Negative COVID-19 Test or Recovery from COVID-19 for All Air Passengers Arriving in the United States Examples of available NAATs for SARS-CoV-2 include but are not restricted to reverse transcription polymerase chain reaction (RT-PCR), reverse transcription loop-mediated isothermal amplification (RT-LAMP), transcription-mediated amplification (TMA), nicking enzyme amplification reaction (NEAR), and helicase-dependent amplification (HDA)
