Understanding immunology and antibody results are imperative to proper code selection and to be able to support any necessary repeat testing. Antibody isotypes IgM assist in attacking infectious pathogens and are indicative of an acute infection. Antibody isotypes IgG are formed as an infection subsides and help the body fight against future attacks from the same bacteria. When the results show IgG positive, it indicates immunity. When a patient has an infection, the results will show IgM positive, but as the IgG antibodies haven't fully formed yet to provide the body with immunity, that result will come back negative.
