A titer test measures the amount of antibodies in a person's blood that are specific to a particular pathogen or antigen. It involves diluting the blood sample and then testing it to determine the highest dilution at which the antibodies are still detectable, which gives an indication of the level of immunity against that pathogen.
A blood test for ana measures the presence of antinuclear antibodies in the blood, which can indicate autoimmune disorders like lupus or rheumatoid arthritis. Results are reported as a titer, with higher titers suggesting a higher likelihood of autoimmune disease. Further testing and evaluation by a healthcare provider are typically required to confirm a diagnosis.
Antigen-antibody reactions are fundamental to the immune system's ability to identify and neutralize foreign substances. They are used in diagnostic tests (e.g., ELISA) to detect the presence of specific antigens or antibodies in samples such as blood. These reactions also play a crucial role in vaccine development and research on autoimmune diseases.
A lavender-capped tube (EDTA tube) is typically used to collect blood for antinuclear antibody (ANA) testing. The EDTA helps prevent clotting and preserves the sample for testing.
An ANA blood test measures the presence of antinuclear antibodies in the blood, which are produced by the immune system. It is often used to help diagnose autoimmune diseases such as lupus or rheumatoid arthritis. A positive result indicates the presence of these antibodies, but further testing is usually needed to confirm a specific diagnosis.

The question is unclear, however If you go to the related link (Antinuclear Antibody Test ) below you Will find detailed information on the Antinuclear Antibody Test
I believe you are referring to a titer. This test can detect a particular amount of antibody in the bloodstream, signalling either the presence of an infection or a built up immunity.
A Titer
An ANA (antinuclear antibody) test is a blood test used to detect the presence of antibodies that may indicate autoimmune disorders. A reflex titer is a follow-up test that is automatically performed if the initial ANA test result is positive, measuring the concentration of these antibodies. This helps in assessing the likelihood of autoimmune diseases, such as lupus or rheumatoid arthritis, and guiding further diagnosis and treatment. A higher titer indicates a greater level of antibodies, which can correlate with disease activity.
