A proposed model for effective collaboration between rheumatologists and clinical pathologists for the diagnosis of autoimmune rheumatic diseases

Tests for detecting autoantibodies are very useful in diagnosing and monitoring autoimmune rheumatic diseases (ARD). However, the continual discovery of new specific autoantibodies and the great advances in laboratory technology have given rise in recent years to the introduction of new tests and new diagnostic methods to the point that the clinician may find himself in difficulty as to which tests should be requested in a given context and how the results obtained should be interpreted.
In fact, if we consider that more than 100 autoantibodies have been described in cases of systemic lupus erythematosus  alone, and that some of these may appear in asymptomatic subjects and may precede the appearance of clinical manifestations by years [2, 3], the ability to differentiate among the results of various methods, which often present differing characteristics of sensitivity and specificity, may cause serious difficulties in the interpretation of test results, certainly on the part of...
