At CTA Pathology, we offer a broad range of dermatopathology and oral pathology services designed to facilitate patient care. In addition to providing traditional immunohistochemical staining and diagnostic reports for skin biopsies, we also offer polymerase chain reaction (PCR) testing for nail diseases and direct immunofluorescence (DIF) for vasculitis, autoimmune bullous and connective tissue disorders. Additionally, we can provide standalone technical and professional components, respectively, in the event that you require slide preparation or the professional read of slides that are already prepared.


Our unique H&E staining staining solution produces ultra-clear images that read smoothly over our digital pathology platform. Please click here for a list of our current special stains.

Direct Immunofluorescence (DIF)

DIF testing illuminates protein buildups and allows our providers to diagnose a range of tricky skin conditions, including autoimmune bullous diseases, connective tissue disorders and vasculitis.

Polymerase Chain Reaction (PCR)

PCR nail testing streamlines the diagnosis of dermatophytes, yeasts and molds. Its highly sensitive process ensures that your office receives quality results within a very short timeframe.
