But with so much ambiguity about how many antibodies are needed for protection Theel is still cautious about endorsing the idea. There are protective antibodies and there are non-protective antibodies.

Theyre very important in fighting viral infections. Each class is designated by a letter attached to an abbreviation of the word immunoglobulin. Many different manufacturers rushed to put antibody tests on the market with little oversight.

Antibodies which are also called immunoglobulins Ig all have the same basic Y-shape but there are five variations on this theme called IgG IgM IgA IgD and IgE said Jason Cyster a. Antibodies defend us against infection by binding to viruses and microbial toxins thereby inactivating them see Figure 24-2.

Specifically the researchers determined that nearly all of the 285 patients studied produced a type of antibody called IgM which is the first antibody that the body makes when fighting an infection. This test can look for multiple types of antibodies including IgG IgM and IgA. Antibodies are proteins made by the immune system to fight infections like viruses and may help to ward off future occurrences by those same infections.

IgA and IgM antibodies were short-lived against the spike protein that crowns SARS-CoV. At this time even. IgG immunoglobulin G antibodies are found in all body fluids and are the most common making up 75 to 80 percent of the antibodies in your body per Michigan Medicine.

The classes of antibody differ not only in their constant region but also in activity. The binding of antibodies to invading pathogens also recruits various types of white blood cells and a system of blood proteins collectively called complement discussed in Chapter 25.
