New automation technologies at the vanguard of IFA diagnostics

EUROIMMUN has been creating innovative solutions for immunofluorescence diagnostics for over thirty years. Continuing this long tradition, the company has over the last year introduced further groundbreaking products to increase the efficiency and standardization of indirect immunofluorescence assay (IFA) analyses. CLI talked to Dr Panagiotis Grypiotis, Head of Product Management Autoimmune Diagnostics, Endocrinology/Biologics and Automation […]

ANCA-IIF: Still the screening method of choice

Systemic vasculitides are a group of inflammatory idiopathic clinical syndromes usually classified by the size of the vessels being affected. Among them, the small vessels vasculitides show clear associations with the presence in the patients sera of antibodies directed against cytoplasmic antigens of neutrophils (ANCA). Thus, circulating antibodies against neutrophil cytoplasm is the most characteristic […]

Molecular allergology offers new opportunities – for the lab and the clinician

Molecular allergology enables quantification of IgE antibodies to single allergen protein components at the molecular level. This helps the clinician establish the cause of allergic sensitisation, evaluate the risk for severe allergic reactions and improve patient management. New tests and technologies enable the laboratory to assist in an efficient manner. by Dr Magnus Borres For […]

Looking at ANA testing from a different perspective

The HEp-2 immunofluorescence assay (IFA) for ANA screening is excellent for ruling out many connective tissue diseases, but a positive result seldom translates into a clinically meaningful diagnosis. A new automated, efficient, enzyme immunoassay for ANA screening provides reliable, objective information that can be applied clinically with confidence.   by James D. Peele, PhD IntroductionFor […]

Autoantibodies against MDA-5: very important serological markers in amyopathic dermatomyositis with rapidly progressive interstitial lung disease

Autoantibodies against MDA-5 are serologically important biomarkers because they are mainly detected in patients with amyopathic dermatomyositis complicated with rapidly progressive interstitial lung disease (ILD). Anti-MDA-5 antibodies are useful not only for diagnosis but possibly also for monitoring disease activity in ILD. by Assoc. Prof. Y. Muro, Assoc. Prof. K. Sugiura and Prof. M. Akiyama […]

LKM Antibodies: skilled pattern recognition

The detection of liver/kidney/microsomal antibodies (LKM) is one of the most common analytical procedures performed in the autoimmunity laboratory. Several techniques can be currently adopted that allow the detection of LKM in patient serum, such as ELISA, line immunoassay or indirect immunofluorescence. Far from being outdated, indirect immunofluorescence is the major method used for the […]

Multiplex autoantibody screening in neurological diseases

The spectrum of autoimmune neurological syndromes has expanded substantially in the last fifteen years because of the discovery of novel anti-neuronal autoantibodies. Today’s autoantibody test portfolio includes over 32 different specificities associated with neurological diseases. Alongside classic anti-neuronal autoantibodies against intracellular targets such as Hu, Yo, Ri, etc are newly identified autoantibodies directed against cell […]
