The HRLMP Clinical Chemistry and Immunology (CCI) labs are located at the Hamilton General Hospital and McMaster University Medical Centre. CCI provides critical lab results that serve as the basis of diagnosis and treatment. A hub of innovation and research, CCI has helped introduce new tests into the community, bolstered the services at local clinics, and helped support other communities across Ontario and the country.


IgG Subclass Testing Now Available in Hamilton

IgG Subclass Testing is a laboratory test used to measure and evaluate the levels of Immunoglobulin G (IgG) in the body. IgG is the most abundant antibody in the human body, making up 75% of serum antibodies, and is responsible for controlling the infection of body tissues. Through this testing, it is possible to identify and diagnose certain conditions, such as autoimmune hepatitis, as well as indicate serologic immunity to certain viruses, such as measles, mumps, Rubella, Hepatitis B, and Varicella.
