Biochemistry Department

General Information

The Biochemistry Department is situated within the Pathology Laboratory at Letterkenny University Hospital.  Biochemistry is concerned with the measurement of the chemical constituents (ranging from ions to complex proteins) of body fluids, for use not only in diagnosis of disease, but also in monitoring the course of disease, the effect of treatment, prognosis and screening. The department provides a comprehensive service during normal working hours (0800-2000 M-F), an urgent service at weekends and bank holidays and a 24 hour emergency service for investigations required for the immediate clinical management of patients.

The Biochemistry User Manual has been prepared in conjunction with The Pathology Department User Manual (MP-GEN-0064) to inform the users of the Saolta University Health Care Group, Letterkenny University Hospital, Pathology Department of which services are available within the Pathology Department and how to obtain the services required.


Documents are available on Q-Pulse and also on the HSE Website

Outside the hours of 09:00 and 17:00 the Medical Scientist “on-call” can be contacted for URGENT requests on 173-814 or via the switchboard at Letterkenny University Hospital (074-9125888).

Urgent Samples

If urgent analysis is required, please call the Biochemistry lab on numbers listed above.

Results and Enquiries

Results will be available for viewing onwards (on Laboratory Information System, KEPLER) following authorisation by the laboratory staff.

Printed reports will be issued daily from the laboratory and delivered to all requesting locations.

Telephoning Results

Abnormal results falling outside defined limits will be telephoned to the requesting source. These limits are available from the Biochemistry Department.

Point of Care Testing (POCT)

Near patient testing devices situated outside the laboratory give high quality results if used and maintained correctly. The laboratory presently only supports POCT for blood gas analysers in NNU, ICU and A&E. All blood gas analysers are password protected and therefore should only be used by staff that have been trained and issued with their own personal password. Please contact 4614 to arrange training when required. All users are personally accountable for any testing performed under their password. The laboratory also provides support for hospital based P.O.C. Glucometers.

External Quality Assurance Schemes

The Clinical Chemistry laboratory participates in relevant external third party assurance schemes.

This includes schemes operated by:

  • UKNEQAS (UK, National External Quality Assurance Scheme)
  • WEQAS (Welch External Quality Assurance Scheme)
  • IEQAS (Irish External Quality Assurance Scheme)
