TITRATION METHOD IN ANTI-NUCLEAR ANTIBODY TESTING FOR THE DIAGNOSIS OF AUTOIMMUNE DISEASES

摘要

The present invention relates to a method for measuring antinuclear antibody titer for diagnosing autoimmune diseases. Antinuclear antibody titer measurement method for autoimmune disease diagnosis of the present invention prepares an antinuclear antibody positive serum test sample from blood collected from a subject, and considers the fluorescence intensity (FI) value or final titer through the subject's past test results to select the serum test specimen (1:80) using diluted serum and the minimum number of dilutions and obtaining the final titer based on the linear slope decreasing trend of the fluorescence intensity (FI) value, a conventional serial dilution series or single-well titration It is effective in diagnosing autoimmune diseases because it is more accurate than the antinuclear antibody test using
