Lymphatic and Immune Systems - Lab Report ExampleSeroconversion is an element of the immune system. When individuals develop antibodies to HIV, medical experts record that they have seroconvert to antibody-positive from antibody-negative (Marieb & Hoehn, 2010).In a direct ELISA test, an antigen is adsorbed to a synthetic plate and then proteins, in excess, are added to stop all the other attach sites using bovine, serum or albumin (Marieb & Hoehn, 2010). In an indirect ELISA test, the steps are similar only that there is an additional step. After the antigen is adsorbed, the close antibody to be included is the antibody that identifies the antigen, unlike in a direct ELISA test.The two tests are antibodies detecting procedures (Marieb & Hoehn, 2010). However, the Western Blot test is considered as a confirmatory test because it can detect HIV early enough for a patient to receive the crucial treatment.The ELISA test is considered extremely pure when it comes to testing for antibo dies and that it why some of its test come back positive (Marieb & Hoehn, 2010). However, the Western Blot test takes its time to establish the status of an antibody, and that is why most of its results are
