What we do

The Histopathology Laboratory is part of the LabMed Directorate at St James Hospital and is one of the largest histology laboratories in the Republic of Ireland, providing a comprehensive service to the hospital itself as well as  to many outside institutuions, general practioners and other hospital nationwide.

The Department offers sub-specialised diagnostic reporting in : Gynecological, breast, lung, gastrointestinal, head and neck, dental, skin, soft tissue, haemato-lymphoid pathology and Cytopathology.  In addition the department carries out hospital and coroner directed post mortems.   It provides diagnostic opinion for patients of St James Hospital, GPs within the Eastern Region, has a large national referral service and contributes to the extensive multi disciplinary team (MDT) meeting schedule of the hospital.

The department offers several excellent diagnostic facilities including automated immunohistochemistry, flow cytometry and molecular diagnostics.

The department is accreditated by INAB ISO15189, 2012.

The Department of Histopathology at St James's Hospital has a strong reputation for post graduate training and research in histopathology.

The academic Department of Histopathology at Trinity College Dublin provides teaching to medical undergraduates in their 3rd and 4th medical years.

Research laboratories are based at St James's Hospital, AMNCH Tallaght and the Coombe Women's Hospital and offer a full range of genomic, functional genomic and proteomic facilities.

Critical Reports

If a diagnosis is deemed “CRITICAL” by the reporting pathologist, examples being unexpected malignancy, unexpected infection in an immunocompromised patient, evidence of a clinical mishap such as a perforated body viscus/ organ, or an unexpected clinically significant inflammatory process such as vasculitis, we we attempt to communicate the report to the clinical team by bleep or mobile telephone number.  Occasionally the consultant pathologist will telephone, email or text message the consultant clinician – this is more common at weekends.  If electronic communication is made only MRN and initials of patient should be used . Details of all such communication are recorded in the report
