Rheumatologic Disorder Diagnostic Testing Patterns: Real World Evidence from a National Laboratory Database

February 21, 2024

Rheumatologic disorders can take years to diagnose, often requiring a combination of specific symptoms, examination findings and laboratory testing, rather than a single test. Additionally, symptoms presenting in rheumatologic processes are often present in other common conditions, making diagnosis challenging. In this study, we sought to examine patterns of post-ANA testing using real world evidence to inform order guidance opportunities and help advance diagnosis.
