This department offers a comprehensive range of diagnostic services in routine Bacteriology, Mycobacteriology, Mycology, Parasitology, Serology and Virology as well as consultation in microbiology, infectious diseases and antibiotic utilisation and provision of statistical and cumulative data for infectious disease monitoring. It has a Public Health Laboratory, which is accredited to the international standard ISO17025 for food, water and hygiene testing.

The proper selection, collection and transport of specimens to the laboratory is, an essential part of the quality assurance of the microbiology laboratory. The laboratory is committed to the use of accredited examination procedures and methods that will ensure the highest achievable quality of all tests performed. Results are reported rapidly and phoned if necessary to ensure timely intervention for optimum patient care.

Scope of the Service

  • Diagnostic Bacteriology including Antimicrobial susceptibility testing.
  • Diagnostic Microbial Serology and Virology.
  • Guidance on Antimicrobial Chemotherapy. See Guidelines attached
  • Guidance on infection Control and Outbreak Management
  • Public Health Laboratory Food and Water testing.

As well as the diagnostic service provided the department has research and educational links with the Faculty of Food Safety in University College Dublin and the Biological Sciences Department in Cork Institute of Technology. It also provides training for student medical scientists and participates in collaborative research work with clinical colleagues. The department is approved by the Royal College of Pathologists for specialist training in Medical Microbiology.

Consultant Microbiologists Dr. Maeve Doyle and Dr. Caroline Fielding are responsible for clinical advice on interpretation of examination results and for authorising the release of reports.

For specific Microbiological testing requirements, please refer to guidelines on collection and transport of specimens and index of specimen containers.

Expected turnaround times are given in routine working days and are based on the time of arrival in the Microbiology Laboratory at Waterford Regional Hospital.

Where appropriate, turnaround times are given for microscopy. Turnaround times for culture are given with a range of times. The lower figure is for a “negative” result (where there has been no follow up of an isolate) and the higher for a “positive” result (where an isolate has been followed up, identified and antibiotic sensitivities determined).  Exceptions are mycobacterial culture, blood culture, and fungal culture, where a negative result is only issued at the end of the incubation period.
