Overview

Careful and extensive investigations in multiple visits to ensure the idiopathic interstitial pneumonia is accurately diagnosed. :*10 to 20% of patients with IPF have positive rheumatoid factor or positive circulating anti-nuclear antibodies (ANAs), but rarely are titers high. However only the presence of high titers (> 1:160) would suggest the presence of a connective tissue disease . [1] [2] [3]*
