SARS-CoV-2-specific IgG antibodies were detected using a commercially available, validated and ICMR-approved kit (Covid Kavach Anti SARS-CoV-2 IgG antibody detection ELISA, Zydus Cadila, India) (Sapkal et al., 2020); the test was performed as per the manufacturer’s instructions. The results were interpreted as positive or negative for SARS Tingkat sensitivitas tes antibodi kuantitatif SARS-CoV-2 cukup tinggi yaitu 98-100 % setelah 14 hari mendapat vaksinasi atau setelah terinfeksi Covid -19. Tidak ada syarat tertentu sebelum melakukan tes ini. Tidak ada batasan usia, riwayat penyakit, jenis kelamin, ras, atau kategori lain sehingga semua orang dapat melakukan pemeriksaan antibodi The COVID-19 pandemic is caused by SARS-CoV-2, a novel zoonotic coronavirus. Emerging evidence indicates that preexisting humoral immunity against other seasonal human coronaviruses (HCoVs) plays a critical role in the specific antibody response to SARS-CoV-2. However, current work to assess the effects of preexisting and cross-reactive anti-HCoVs antibodies has been limited. To address this All EDSAB-HOME samples were first tested with two laboratory immunoassays: Roche Elecsys®, which measures total (including IgG and IgM) antibodies against the Nucleoprotein, and EuroImmun Anti-SARS-CoV-2 ELISA assay, which measures IgG antibodies against the S protein S1 domain. Any immunoassay failing for technical reasons was repeated. The SARS-CoV-2 IgG is authorized for the detection of IgG antibodies to SARS-CoV-2 in human serum, serum separator tube and plasma (ACD, CPD, CPDA-1, The average time to detect IgG against SARS-CoV-2 based on RBD IgG-ELISA was similar to what was found in other studies, regardless of the serological assay and SARS-CoV-2 antigen used 26,51,52,53 Between April 18 and June 17, 2020, 330 HCWs from five Madinah region-affiliated hospitals underwent a seroprevalence screening for anti-SARS-CoV-2 antibodies (immunoglobulin [Ig]M/IgA and IgG) using indirect ELISA testing. Result. Among the 330 samples, 80 (24.24%) were positive for SARS-CoV-2 IgM/IgA and/or IgG antibodies. 3IBQv4.
