Care at NUH

Laboratory Medicine

2024/06/14

Established in May 1988, NUH's Department of Laboratory Medicine has evolved significantly over the years; adapting not only its physical environment but also refining its operational processes. We continuously stay at the forefront of advancements in laboratory methodologies and technologies. The NUH core laboratory boasts an automated and state-of-the-art chemistry and haematology track system. Our microbiology laboratory operates a fully certified BSL-3 facility. We also offer cytogenetics testing and a molecular diagnosis centre with a proven track record of excellence.  

"We aim to lead in providing laboratory services designed to assist our customers with the diagnosis and treatment of disease, the promotion of health and the advancement of medical science"

We offer an extensive test menu that supports our healthcare professionals in screening, diagnosing and treating patients at NUH and in the region. Comprehensive internal and external quality assurance programmes are in place to ensure high-quality patient testing. Our laboratories are fully accredited by the College of American Pathologists, the American Association of Blood Banks, and ISO 15189:2012, among others.  

Our department is staffed by a team of qualified staff, including both medical and doctorate professionals, who have received training and certification in various areas including clinical chemistry, haematology, microbiology, transfusion medicine, molecular diagnostics, cytogenetics and flow cytometry. Additionally, we offer comprehensive overseas referral services for tests not available in Singapore. 

Quality & Accreditation

The Department of Laboratory Medicine is committed to providing our patients and clinical clients with high quality laboratory services, consistently striving to surpass expectations. 

To ensure sustainable quality, we regularly review our testing journey – from order to blood collection, specimen transportation, analytical processes in the laboratory and the release of results to the ordering clinician. 

Our internal quality control processes provide our staff with a review of the accuracy and precision of each analyser and test, ensuring confidence in the testing of patient samples. Complementing these internal processes, mandatory external quality control procedures provide a periodic peer review comparison of our laboratory performance.  

A key component of our quality management programme is continuous quality improvement, achieved through regular reviews of the quality and appropriateness of our laboratory services. Routine internal audits are conducted to assess adherence to our management programme, offering a platform for the evaluation of newly implemented processes and the maintenance of ongoing processes.
