Immunoglobulin G and immunoglobulin M positivity in relation to coronavirus disease 2019 severity

ObjectiveThe aim of this study was to evaluate the seropositivity rapid immunoglobulin G (IgG) and M tests in patients recovered from coronavirus disease 2019 (COVID-19).BackgroundRapid severe acute respiratory syndrome 2 (SARS-CoV-2) antigen-detection can give results less than 30 min detect SARS-CoV-2.Patients methodsThis case–control performed Toluca, Mexico, September October, 2020. Rapid test older 18 years who were diagnosed with COVID-19. Quantitative data presented as mean ± SD qualitative percentages. Pearson correlation between COVID-19 clinical severity scale waist BMI variables.ResultsTwenty-five included (mean age, 45.24 years). Through correlation, a positive relation found score circumference (R2 = 0.161, P 0.046844) first 0.157, 0.049918). The 23.12 15.23. Sixty-eight percent obtained for detection IgG antibodies. In exceed manifestations, all antibodies against SARS-COV-2 after several months.ConclusionPatients comorbidities had higher predisposition more disease, highest intensity signs symptoms, immunological response, probability having over time.
