Diagnostic Performance of 2019-nCoV Ab Rapid Test Kit for Detection of Probable Asymptomatic Cases of SARS-CoV-2 on Residents of Quezon Province

Antibody testing, also known as serology testing is usually performed when an individual has completely recovered from having COVID-19 infection. Collecting and testing a blood sample of a patient who had such an infection could help determine if the patient or individual has developed antibodies against the COVID-19 virus. The positive result of having antibodies means that a patient or individual has had COVID-19 infection. Right timing is also important because it affects the accuracy of the result. In the event that testing is performed too soon in the course of infection, when the insusceptible reaction is still developing in your body, the test may not identify the antibodies. So immune response testing is not suggested at any rate until 14 days after the beginning of the symptoms. The researchers have chosen this study to determine if the rapid Ab testing kit can be used as a method in determining the presence of COVID-19 infection. This COVID-19 IgG/IgM rapid antibody test kit is qualitatively designed to detect the presence of the IgM and IgG antibody against the COVID-19 virus in a patient's serum/plasma. The participants' results detected neither IgG or IgM antibodies. Accordingly, the researchers conclude that the result could be true negative or the ab rapid testing was done too early in the course of onset of the disease to the frontliners. Therefore, the researchers conclude that the Ab rapid COVID-19 IgM/IgG test kit is not recommended as an independent diagnostic method in acute SARS-CoV-2 infection.
