Antinuclear Antibody Screen and Titer

The Antinuclear Antibody (ANA) Screen with Titer and Pattern evaluates the presence of antinuclear antibodies in the blood, which can indicate autoimmune activity. When antibodies are detected, additional analysis determines their concentration (titer) and staining pattern, providing important context for identifying specific autoimmune or connective tissue disorders. This test is commonly used in the evaluation of symptoms such as joint pain, fatigue, rashes, or unexplained inflammation, and it supports diagnosis, risk stratification, and ongoing management of autoimmune conditions.
