Medical tests used in immunology and for inflammation CPT — Antigen diffuses into the agar which contains specific antibody and a ring of precipitate is formed, the diameter of which is directly proportional to the concentration of the antigen and can thereby be used to quantitate the amount of antigen.

For most antigens, the area and the square of the diameter of the circle at the circle’s end point are directly proportional to the quantity of antigen and are inversely proportional to the concentration of antibody. American Association for Clinical Chemistry.

Webarchive template wayback links CS1 maint: Circles that small quantities of antigen create reach their end points before circles that large quantities create. Radial immunodiffusion RID or Immunoddiffusion method, Mancini immunodiffusion or single radial immunodiffusion assay, is an immunodiffusion technique used in immunology to determine the quantity or concentration of an antigen in a sample.

Immunoassays in Coagulation Testing. Therefore, precipitation near the center of the circle is usually less dense than it is near the circle’s outer edge, where antigen is less concentrated.

Diagnostic immunology Nephelometry Complement fixation test Immunocytochemistry Immunohistochemistry Direct fluorescent antibody Epitope mapping Skin allergy test Patch test. Measurements of large circles are more accurate than are those of small circles. The antigen diffuses radially into the medium, forming a circle of precipitin that marks the boundary between the antibody and the antigen.

The molten medium is then poured onto a microscope slide or into an open container, such as a Petri dishand allowed to cool and form a gel.

While circles are still expanding, a graph that compares the quantities or concentrations of the antigen immunodjffusion a logarithmic scale with the diameters or areas of the circles on a linear scale may be a straight line kinetic method.
