![]() ![]() In both tests, a false negative result (a negative result when the test is actually positive) might occur at the early stages of infection because there are insufficient levels of the virus in your body. It is useful in clinics with a limited number of clinical laboratory specialists, in time-sensitive emergency medical situations, in medical facilities in areas where the infection is spreading, and in elderlyĬare facilities for testing individuals with no symptoms. Rapid antigen test is a method that often does not require special techniques or equipment and can provide results on-site inġ5-30 minutes. Within a short period of time and at medical facilities that test a large number of patients. Thus, it is used at airport quarantine, where results of a large number of tests are required In addition, the use of a fully automated system allows for the simultaneous processing of multiple tests. The results can be obtained withinĪs little as 30 minutes. The high-sensitivity quantitative antigen test has the same accuracy as the PCR test except in cases of low levels of virus in your body when infectivity is often low. There are two types of antigen tests: the high-sensitivity quantitative antigen test and ![]() The reliability of the results can also vary from facility to facility.Ĭaution is needed when using this test as it can detect non-infectious viruses in your body even after you recover from infection. However, reports have shown varying results using different reagents. Nucleic acid detection test, including PCR test, is a highly sensitive testing method. is not recommended for screening of asymptomatic patients.is useful for those who are at risk of spreading the infection to others and have sufficient viral load to be detectable.could give a false-negative result (a negative result despite being infected) when the viral load is not above a certain level.is effective when a wide range of tests are required, such as in areas where the infection has spread.does not require any special equipment and can give a result at the site.can give a result within 15 to 30 minutes.may require retesting due to non-specific reaction in some cases.can be performed using specialized equipment used in general laboratories.enables a fully automated system that allows for high-throughput (mass processing) testing using specialized equipment.can be used from symptomatic to asymptomatic screening.has the same level of detection accuracy as some nucleic acid detection test.■ Features of the high-sensitivity quantitative test ![]()
