We’ve all heard the phrase, “when you see a doctor, you should see a specialist.” You should see one because you will get a specialist’s opinion on your symptoms. You should see a specialist because a specialist will be able to offer you a more accurate diagnosis, a diagnosis that may include an immunoassay test.
Immunoassay tests are used to determine whether your symptoms are caused by a physical or biological condition. They are commonly used in hospitals to check for specific diseases, and in the clinical laboratory to check specific proteins within a sample.
Immunoassay tests are designed to determine the presence of specific blood proteins. They are often used to diagnose diseases and monitor the effectiveness of drugs and other treatments.

Immunoassay is the process of testing for proteins that are present in a biological sample. This is also used to check for diseases such as cancer. The process of testing involves mixing a sample with a specific antibody or drug (or both) and then adding a small amount of a complementary protein that you want to use in the test.
In immunoassay, the sample is first tested to confirm that there is a specific antibody or drug in it. Then the sample is washed with a fluid that contains a chemical that specifically binds to the specific protein to be tested. If the sample contains the desired protein, it will bind to the complementary protein and the test result will change.
When a sample is mixed with a mixture of antibodies (that in turn contain multiple antibodies) the antibodies in the mixture may bind to each other, resulting in a complex mix that can be quantified. It is then important to know which antibody or antibody combination is in the sample before you begin the test. In immunoassay, we often use the colorimetric dye eosin-naphthol to help us know which antibody is in the sample.
I really like the colorimetric eosin-naphthol, but the point is that you can also use a “chemiluminescent” assay. Which is basically a sample in which some of the antibodies have been added and some of the antibodies are not. In this case, the antibodies are added simultaneously and the sample is shaken and colored. Then, the result is read.
The chemiluminescent test is what we were referring to with the dye. The chemiluminescent test is also a colorimetric assay but you don’t have to shake. The problem with the colorimetric assay is that the sample might have other substances in it that might interfere with the color. The chemiluminescent test, you have to shake the sample.
Immunoassay techniques involve an antibody that is specifically designed to bind to a substance in the sample. The antibody has a molecular weight and specific binding properties and is coated to a solid matrix, such as a well in a test tube. When the sample (which contains the target substance) is added to the well, the molecule that the antibody recognizes is captured by the solid matrix. When the sample is shook, the antibodies in the well bind to that substance.
