Comparative evaluation of six immunoassays for the detection of antibodies against SARS-CoV-2 |pdf=|usr=}}{{33338544}} gab.com Text Comparative evaluation of six immunoassays for the detection of antibodies against SARS-CoV-2 JO: J Virol Methods http://www.kidney.de/pget.php?&tw=1&pmid=33338544 #FOAvip OBJECTIVES: Serologic techniques can serve as a complement to diagnose SARS-CoV-2 infection. The objective of our study was to compare the diagnostic performance of six immunoassays to detect antibodies against SARS-CoV-2: three lateral flow immunoassays (LFAs), one ELISA and two chemiluminescence assays (CLIAs). METHODS: We evaluated three LFAs (Alltest, One Step and SeroFlash), one ELISA (Dia.Pro) and two CLIAs (Elecsys and COV2T). To assess the specificity, 60 pre-pandemic sera were used. To evaluate the sensitivity, we used 80 serum samples from patients with positive PCR for SARS-CoV-2. Agreement between techniques was evaluated using the kappa score (k). RESULTS: All immunoassays showed a specificity of 100 % except for SeroFlash (96.7 %). Overall sensitivity was 61.3 %, 73.8 %, 67.5 %, 85.9 %, 88.0 % and 92.0 % for Alltest, One Step, SeroFlash, Dia.Pro, Elecsys and COV2T, respectively. Sensitivity increased throughout the first two weeks from the onset of symptoms, reaching sensitivities over 85 % from 14 days for all LFAs, being One Step the most sensitive (97.6 %), followed by SeroFlash (95.1 %). Dia.Pro, Elecsys and COV2T showed sensitivities over 97 % from 14 days, being 100 % for COV2T. One Step showed the best agreement results among LFAs, showing excellent agreement with Dia.Pro (agreement = 94.2 %, k = 0.884), COV2T (99.1 %, k = 0.981) and Elecsys (97.3 %, k = 0.943). Dia.Pro, COV2T and Elecsys also showed excellent agreement between them. CONCLUSIONS: One Step, Dia.Pro, Elecsys and COV2T obtained the best diagnostic performance results. All these techniques showed a specificity of 100 % and sensitivities over 97 % from 14 days after the onset of symptoms, as well as excellent levels of agreement.
