Laboratory tests. the fluorescent antibody test uses fluorescent tags that are attached to antibodies for easy detection.
fluorescent antinuclear antibody test, a test for antinuclear antibody components; used, in particular, for the diagnosis of collagen-vascular diseases.
a second antibody is added to the mixture. This antibody is "tagged" with a fluorescent dye so that it can be seen. The second antibody attaches to any antibodies and cells bound together

The antinuclear antibody test of blood is usually negative in Raynaud's disease
An example of a antibody-based test that can be bought at your local pharamacy wouldbe a Pregnancy Test. a pregnancy test is pretty much an ELISA.
A positive result on an antinuclear antibody (ANA) test may indicate the presence of autoimmune diseases such as lupus or rheumatoid arthritis. It suggests that the immune system is producing antibodies that mistakenly target normal proteins in the nucleus of cells. Further diagnostic testing is often needed to confirm a specific autoimmune condition.
DefinitionSputum direct fluorescent antibody (DFA) is a test that looks for microorganisms in lung secretions.Alternative NamesDirect immunofluorescence test; Direct fluorescent antibody - sputumHow the test is performedYou will produce a sputum sample from your lungs by coughing up mucus from deep inside your lungs. (The mucus is not the same as saliva or spit from the mouth.)In the laboratory, antibodies that have been chemically linked to a fluorescent dye are added to the sample. These antibodies are considered "tagged." They will attach to specific antigens-- in this case, the microorganism against which they were formed. If the specific microorganism is present, a bright glow (fluorescence) can be seen in the sputum sample using a special microscope.How to prepare for the testIf coughing does not produce sputum, a breathing treatment may be given before the test to trigger sputum production.How the test will feelThere is no discomfort.Why the test is performedYour doctor may order this test if you have signs of certain lung infections or pneumonias.Normal ValuesNormally, there is no antigen-antibody reaction.What abnormal results meanAbnormal results may be due to an infection such as Legionnaire's disease, mycoplasma pneumonia , or chlamydia pneumonia.What the risks areThere are no risks.
