First level information About Clinical Relevance & List of Abbreviations |
▶ The AC-25 pattern has low positive predictive value for any disease (109) ▶ Found very infrequently in a routine serology diagnostic setting (109) ▶ Antigen recognized includes HsEg5; specific immunoassays for this autoantibody, or other spindle fiber targets, are currently not commercially available (110, 111) |
