Does a newly developed ELISA system accurately detect anti-ARS antibodies compared to RNA immunoprecipitation in patients with connective tissue disease and idiopathic interstitial pneumonia?
A newly developed ELISA system using a mixture of recombinant ARS antigens demonstrates high sensitivity and specificity for detecting anti-ARS antibodies, comparable to RNA immunoprecipitation, enabling easier clinical use.
