The scientific study of bodily fluids and other serums in the body. Most of the time it refers to diagnosing antibodies or immunoglobulins, which are large Y-shaped proteins. Antigens are substances that provoke a response from the immune system, and antibodies are what the body produce to protect your immune system. The most common kinds of antigens are bacteria, fungi, viruses, and parasites. To conduct a serologic test, all that is needed is a blood sample. An agglutination analysis shows whether antibodies exposed to certain antigens will cause particle clumping. A precipitation test shows whether the antigens are similar. They do so by measuring for the presence of antibody in body fluids.The Western blot test detects if antimicrobial antibodies are in your blood by their reaction with target antigens.

Plasma is the clear, light yellow colored liquid portion of blood that stays after red blood cells, white blood cells, platelets and other cellular components are removed. It is the largest component of human blood, making up about 55 percent. It contains water, salts, enzymes, antibodies and other proteins. The main purpose of plasma is to transport hormones, nutrients, and proteins to various parts of the body. Plasma helps remove waste from the body after cells deposit their waste products into them. Blood Plasma also help the movement of blood throughout the body.

Antibodies, which are also called immunoglobulins, are large Y-shaped proteins. They identify and help remove foreign antigens or targets to the immune system such as bacteria, fungi, viruses, and parasites. The five classes of immunoglobulins are IgM, IgG, IgA, IgD, and IgE. However, the basic structure of all antibodies are the same. They work by binding to specific antigens. Then that signals the other cells of the immune system to get rid of the invading microbes.

An antigen is any substance that causes your immune system to produce antibodies against it. This means your immune system does not recognize the substance, and is trying to fight it off.

A cell that contains hemoglobin and can carry oxygen to the body. Also called a red blood cell (RBC). The reddish color is due to the hemoglobin and is what makes the blood red.

This is the most important blood type system and is important for blood transfusions. They are found on platelets, epithelium, and cells other than erythrocytes, as well as AB antigens. ABO Blood type antigens are not just found on the surface of red cells, but are also normally secreted by some people in their body fluids, including saliva, tears, and urine.
