There is an important need for specialised biological and immunological tests in the care of patients being treated with biologic agents. For example, unwanted immunogenicity can lead to loss of effectiveness or even severe adverse reactions. Risks are likely to increase with chronic or repeated administration. BioAnaLab welcomes enquiries from clinicians and hospital-based laboratory scientists who require special immunoassays or bioassays. This service is supported by BioAnaLab's team of clinical advisors who have experience of using biopharmaceuticals in a range of specialities, including Clinical Immunology, Haematology, Rheumatology, Transplantation and Neurology.
