[Methods of autoantibody diagnostics - when immunofluorescence test, when ELISA?]

Area of Science:

• Clinical Immunology
• Autoimmunity Research
• Diagnostic Biomarkers

Background:

• Autoantibodies are key to diagnosing systemic and organ-specific autoimmune diseases.
• Autoantibody detection aids in classification, diagnosis, and prediction of disease onset.
• Early detection of autoantibodies can precede clinical manifestation by years.

Approach:

• This review examines the evolution of laboratory methods for autoantibody detection.
• It contrasts conventional (monoplex) assays with advanced multiplex platforms.
• Various diagnostic immunoassays currently used in clinical practice are presented.

Key Points:

• Immunoassays are vital for identifying autoantibodies against cellular molecules.
• The development of autoantibody detection methods marks significant progress in clinical immunology.
• Multiplex platforms enable simultaneous quantification of numerous autoantibodies.

Conclusions:

• Accurate autoantibody detection is fundamental for autoimmune disease diagnosis and management.
• Advancements in immunoassay technology have significantly improved diagnostic capabilities.
• Understanding autoantibody profiles aids in early disease prediction and personalized medicine.
