Recommendations for the use of anti-dsDNA autoantibodies in the diagnosis and follow-up of systemic lupus erythematosus - A proposal from an expert panel.

Anti-dsDNA autoantibodies are listed as one of the classification criteria for systemic lupus erythematosus (SLE) and are relatively effective indicators for monitoring disease activity and treatment response. Therefore, clinicians rely on them to diagnose and adjust medication and treatment strategies for SLE patients. However, the use of anti-dsDNA antibodies is not free from controversy.

Evaluation of five widely used serologic assays for antibodies to SARS-CoV-2.

Reliable diagnostic technologies are pivotal to the fight against COVID-19. While real-time reverse transcription-polymerase chain reaction (rRT-PCR) remains the gold standard, commercial assays for antibodies against (SARS-CoV-2) have emerged. We sought to examine 5 widely used commercial methods.
