Course Description: This course concentrates and expands upon both the diagnosis and laboratory testing for autoimmune diseases, as well as on the interpretation of antinuclear antibody (ANA) staining patterns. Laboratory methods for detection and identification of ANAs are complex. Proper training is required to correctly interpret results at both the laboratory and clinical level. This educational program provides a comprehensive review of the methods, interpretation, and clinical significance of ANA testing. The material presented will describe various autoimmune diseases with emphasis on diagnosis using laboratory&a
