The research aimed to determine the concentrations of IgG and IgM antibodies for different intervals after recovery from Covid-19, namely 4, 6 and 8 months; the research also aimed to identify the accordance between two types of immunity techniques used to identify the existence of antibodies. The results showed the existence of IgG antibodies with a percentage of (94.03%), and IgM antibodies with a percentage of 55.22% in individuals under study when using ELISA technique. The percentages of these antibodies were (86.56%) for IgG and (16.42%) for IgM when using Rapid test cassette in diagnosis; the matching was 67% between the two methods. Samples of the control group also showed the presence of IgG and IgM with percentages of 68% and 88% respectively.The average concentrations of IgG antibodies were 33.05, 43.21 and 37.53 after 4, 6 and 8 months after infection respectively; the peak was at the 6th month after infection. The averages of IgM were 14.45, 18.52 and 19.18 after 4, 6 and 8 months of being infected respectively; the peak was at the 8th month after infection.
