Reporting the CENP-F-like (AC-14) antinuclear antibody pattern in the internet age: a case report.

Laboratories can play a crucial role in supporting clinicians, providing confirmation of laboratory results, even in the absence of commercial tests for determining the antigenic specificity. We believe that this case exemplifies the importance of correct and careful laboratory reporting, especially in an era where patients frequently engage in self-diagnosis. It also underlines the value of multidisciplinary collaboration in the management of unexpected laboratory results.
