​​​​​​​Clinical Immunology Laboratory

​ ​

The Clinical Immunology Laboratory (CIL) of Tan Tock Seng Hospital provides diagnostic tests that are vital for the management of patients with rheumatologic, allergic or immunologi​c diseases.

We offer the complete range of clinically relevant investigations that are performed accurately and expeditiously. These include autoantibody tests for systemic and organ-specific autoimmune dis​eases, various serological tests for syphilis, genotyping for HLA-B27 and HLA-B*5701, total and specific IgE​ to various aeroallergens and food allergens.

This laboratory service was initiated by clinicians to fulfill a clinical role and this has remained our mission. The range of tests and the way they are reported are designed to aid the clinician in his or her practice. The laboratory is under the charge of a practising Rheumatologist who is available for discussions about the test interpretation.

Quality is very important to us. We subscribe to two external audit programs: the National External Quality Assurance Scheme (NEQAS) from UK and the College of American Pathologists (CAP) Survey from the USA. For tests that are not offered by the CIL, our personnel will help the physician source for an alternate accredited laboratory and arrange the transport of the specimen.

Our laboratory has been accredited by the CAP since 2001.

Immunology Research Laboratory

​The Immunology Research Laboratory (IRL) was restructured from the department's Autoimmune Research Laboratory (ARL). The ARL was set up by the Department of Rheumatology and Immunology in 1994 for the purpose of research in autoimmune systemic rheumatic diseases.

In 1999, the ARL was restructured into the Clinical Immunology Laboratory (CIL) which supports the clinical services of the department and hospital, and the Immunology Research Laboratory (IRL) which supports the department's research in rheumatology, clinical immunology and allergy.

The IRL is presently funded through research grants. Our main research interests are in SLE, rheumatoid arthritis and drug allergy.
