St James's Hospital in Dublin is going to start testing patients for HIV.
All patients admitted to its Emergency Department will be tested for HIV, hepatitis B and hepatitis C.
The hospital treats over 45,000 patients in the Emergency Department every year.
These new routine tests will aim to help diagnose new cases and provide the appropriate care to patients.
St James's Hospital says the testing is in line with international best practice and comes following the pilot project, which highlighted a prevalence of all 3 blood-borne viral infections amongst Emergency Department patients.
