产品描述
The product CSB-EL33241HU is an easy-to-use ELISA Kit intended for the qualitative detection of SARS-CoV-2 S1 RBD IgG antibody in human serum and plasma in vitro. SARS-CoV-2 S1 RBD IgG is an indicator of a recent or prior COVID infection. Infected patients develop IgG against SARS-CoV-2 S1 RBD 7 days post-infection, and IgG content peaks in the third week (IgM was close to vanishing at this time). IgG lasts in the blood for months or even years. After secondary infection, IgG levels in the body of patients increase rapidly and substantially in the short term and remain in the body for a long time, while IgM rarely increases. Serological testing may help to diagnose suspected patients with negative RT–PCR (real-time polymerase chain reaction) results and identify asymptomatic infections.
