Biopharma Solutions - Research & Discovery

We offer a comprehensive menu of tests covering complement activation in autoimmune diseases, including proprietary diagnostic testing for Cell-Bound Complement Activation Products; BC4d, and EC4d.

These biomarkers are the most reliable, sensitive and stable indicators of the complement activation system, which is central to the lupus disease process and critical in early diagnosis & monitoring of systemic lupus erythematosus (SLE), lupus nephritis, autoimmune and many more inflammatory and complement mediated diseases.
