The significance of reliable testing methods has grown rapidly over the course of COVID-19. Healthcare companies introduced many accessible screening methods and kits to identify infected individuals. These methods play a vital role in ensuring public safety and decrease any risks of further outbreaks. It further helps people with following their quarantine guidelines. Therefore, finding the best COVID-19 test is more than necessary. In that sense, people should learn the different screening methods and their uses to make an informed decision. PCR Polymerase Chain Reaction detects the presence of viral RNA before any symptoms are present. Therefore, this screening allows doctors to identify patients much earlier in their illness. During PCR procedures, physicians will add revere transcriptase to nasopharyngeal samples. These substances make many copies of Viral RNA and signal a positive result. Hence. Healthcare workers can quarantine infected patients and break the transmission chain. Modern advances further refined this procedure with the addition of automation. These developments further reduce the chances of any false-positive results. Lateral flow
Similar to PCR, Lateral flow tests detect active viral infection rather than antibodies. Doctors will place nasopharyngeal samples with a small absorbent pad. This material binds to SARS-Cov-2 proteins and indicates positive results with a colored line. Therefore, there is no need to wait for confirmation. The test can produce indicators within 15 or 30 minutes. However, they might lack accuracy when applied to mass segments of the population. Antibody An antibody testing method indicates the proportion of infection in the population. It takes about two or three weeks to generate results. Opposed to swabs, antibody methods use blood samples because there will be a measurable presence of virus in the body. It can also evaluate the immune response of a person to prevent any severe complications. Choosing the right COVID-19 test The ideal screening method depends on many factors, such as objectives and infection symptoms. Experts suggest combining different testing procedures to get accurate results for a situation. It further helps the public health department with preventive measures and programs.
