Abstract

In this paper, using Covid-19 diagnostic data provided by the Korea Disease Control and Prevention Agency (KDCA), we examine the probability of confirmed cases and the probability of actually being confirmed when the rapid test is negative according to the sensitivity and specificity of the rapid diagnostic kit. When we know the conditional probability of confirmation given a positive test, we induce the relationship between sensitivity and specificity, and compute the actual sensitivity of the rapid diagnosis kit based on the data of KDCA.

이 논문에서는 질병관리청에서 제공한 코로나 진단검사 관련 자료를 이용하여 신속진단키트의 민감도 및 특이도에 따른 확진 비율과 신속검사에서 음성이 나왔을 때 실제로는 확진이었을 확률에 대해 알아본다. 또한 양성 반응 중 실제 확진의 확률을 알 때 민감도와 특이도 간의 관계를 유도하고 이를 통해 질병관리청의 자료에 따른 신속진단키트의 실제 민감도가 얼마나 되는지 알아 본다.
