RT-PCR, reverse transcription polymerase chain reaction.
aThe P value for the comparison of age between test results is calculated with the use of the Kruskal-Wallis test with median (Q1, Q3). The P value for the comparison of sex, race, and job categories by testing result is calculated with the use of the χ 2 test and Fisher exact test.
