Quizplus · Accepted Answer

Radial immunodiffusion testing is commonly used to measure the concentration of specific antibodies in a person's serum. It involves placing a sample of serum containing the antibodies into a well in a gel matrix that also contains a known amount of the specific antigen. The antibodies in the serum then diffuse outward from the well and eventually form a visible ring where they have precipitated with the antigen. The diameter of the ring is directly proportional to the concentration of antibodies in the serum. This method is often used to monitor antibody responses to vaccinations, track disease progression, and assess immune function.
