Nepean Hospital's new Pathology Department was officially opened on Tuesday 8 August 2023, providing staff the latest in cutting-edge medical technology to perform vital diagnostic testing. The new facility, which was fast tracked as part of Stage 2 of the redevelopment, is one of the first NSW Health Pathology laboratories to be fitted with advanced new chemical pathology analysers, and will provide a range of common tests such as liver and kidney function tests and diabetes monitoring. The department will be in a larger, purpose-built facility and provide significantly expanded pathology services to meet the needs of the growing local communities and boost health outcomes in the region. At around 1.5 times larger than the previous laboratory, the expanded lab will revolutionise the way staff work and enhance the services and facilities available to patients being treated at Nepean Hospital.
