The Korea Electronics Technology Institute (KETI) has developed a device that measures the results of an antigen and antibody immune response test, one of simple influenza tests, faster and more accurately.

KETI announced on April 7 that the newly developed high-performance immunodiagnostic reader digitizes and accurately measures the results of a test from a rapid diagnosis kit.

A rapid diagnosis kit can be used to quickly and easily determine the presence or absence of a disease within about 10 minutes through an antigen and antibody immune response test by injecting a test sample of a patient's blood, urine, or body fluid. Typically, it is used for self-diagnosis of pregnancy or simple tests for flu.

Recently, it has been widely used for rapid on-site diagnosis of three major infectious diseases -- dengue fever, influenza, and pandemic hemorrhagic fever. However, in the case of the COVID-19 virus, the Korea Center for Disease Control is using a quasi-diagnostic method instead of an antigen-antibody rapid diagnosis kit to boost accuracy.

KETI’s quantitative reader has improved performance by more than three times and reduced the time required from 10 seconds to less than 3 seconds compared to currently commercially available time-division type (TRF) readers. In particular, the image analysis program that automatically recognizes and quantifies a test line area enhances user convenience.
