ANCA-associated vasculitis: the 2022 ACR/EULAR classification criteria and the role of IVD antibody testing

ANCA antibody testing plays a central role in the 2022 American College of Rheumatology/European Alliance of Associations for Rheumatology (ACR/EULAR) classification criteria for ANCA-associated vasculitis (AAV). A recent study evaluating these criteria in children provides a useful entry point into the classification of AAV. Although the criteria were developed from adult cohorts, the pediatric analysis […]

Anti-phospholipid Antibodies (aPL) as Prognostic Markers

Anti-phospholipid antibody (aPL) testing is used in the evaluation of suspected antiphospholipid syndrome (APS). aPL may also be detected in patients with systemic lupus erythematosus (SLE) and can inform the assessment of APS-related thrombotic or obstetric risk when interpreted together with established clinical criteria. A recent 10-year cohort study published in The American Journal of […]

Understanding Scleroderma and Its Diagnostic Tests

June is recognized as Scleroderma Awareness Month to honor those affected by the disease. The month ends with World Scleroderma Day on June 29. This date commemorates Swiss painter Paul Klee, who died of systemic sclerosis in 19401. Scleroderma, or systemic sclerosis, is a rare autoimmune disease. It causes hardening and tightening of the skin […]

AI-Based ANA HEp-2 IFA Interpretation: Clinical Validation in Routine Diagnostics

Antinuclear antibody (ANA) testing by indirect immunofluorescence assay (IFA) on HEp-2 cells is widely used as a reference screening method for systemic autoimmune rheumatic diseases (SARD), including systemic lupus erythematosus, systemic sclerosis, and Sjögren’s syndrome. However, manual interpretation of ANA HEp-2 IFA patterns is time-consuming, operator-dependent and subject to inter-observer variability. A recent study published […]

Serological Biomarkers in Primary Sclerosing Cholangitis (PSC): Focus on anti-GP2 IgA

Primary sclerosing cholangitis (PSC) is a chronic, progressive inflammatory disease affecting the bile ducts and often leading to fibrosis, cirrhosis, and eventually liver failure. PSC also carries an increased risk of hepatobiliary malignancies, particularly cholangiocarcinoma. Despite significant research efforts, PSC remains difficult to diagnose and manage because its pathogenesis is not fully understood and reliable […]

Variability in Diagnostic Test Results

Understanding Normal Analytical Variation In diagnostic testing, it is not uncommon to observe small differences when the same sample is measured repeatedly. Such variations are expected and reflect the inherent characteristics of the assay, even under well-controlled laboratory conditions. Diagnostic assays rely on complex biological, chemical, and technical processes. Each step introduces a degree of […]

Anti–Factor H Autoantibodies and ELISA Testing: Optimizing Diagnosis in Atypical Hemolytic Uremic Syndrome (aHUS)

Atypical hemolytic uremic syndrome (aHUS), also known as complement-mediated thrombotic microangiopathy (CM-TMA), is a rare but life-threatening condition caused by dysregulation of the alternative complement pathway. Among the known etiologies, autoantibodies against complement factor H (anti-factor H) play a critical role, accounting for approximately 10% of cases. Accurate laboratory detection of these antibodies is essential, […]

Cholera and Guillain–Barré Syndrome: When Epidemics Trigger Autoimmune Neuropathy

In regions affected by recurrent cholera outbreaks, overlapping infectious diseases can obscure the diagnosis of post-infectious autoimmune conditions. We recently collaborated in the publication describing a pediatric case from Yemen that illustrates how Guillain–Barré Syndrome (GBS) can emerge during a cholera outbreak, highlighting the critical role of Campylobacter jejuni infection and anti-ganglioside antibody testing 1.
