G (IgG). People with IgG deficiency are more likely to get infections. When your body feels it is under attack, it makes special proteins called immunoglobulins or antibodies. This may mean taking a daily antibiotic to ward o

Place separated serum into a standard transport tube within 2 hr of collection. Normal findings IgG antibodies without IgM means a past mono infection. People with very low immunoglobulin levels, especially IgA, IgG, and IgM, have a higher chance of developing an infection. A very small number of people cannot make IgA and have a higher chance of developing a potentially life-threatening reaction to a blood transfusion. detectable IgG antibody response is consistent with the latter two scenarios. 3) IgM + } IgG + } Antibody response is consistent with recent infection and/or immunization. 4) IgM -} IgG + } Presence of IgG antibodies in the absence of detectable IgM is consistent with past infection, prior vaccination, or ongoing infection (e.g.

High Immunoglobulin M. There are two types of IgM antibodies: natural and immune [1, 3]. The body produces immune IgM antibodies in response to intruders (antigens).
