Affordable Autoimmune Test Matches Established Assays

Study suggests a simplified multiplex approach could expand ENA antibody testing in routine and resource-limited laboratories

1

A new multiplex assay for ENA antibodies shows diagnostic performance comparable to established immunoassay platforms.
2

The assay uses a standard 96-well plate format, making it easier for laboratories to adopt without significant capital investment.
3

Agreement between the new assay and established methods was strongest for certain antibody targets, reflecting variability in ENA assays.
4

The assay demonstrated reproducibility across manufacturing lots and production batches, supporting its analytical consistency.
5

The study highlights limitations, including comparisons against commercial assays rather than clinical outcomes or independent standards.
