Page Type
Product Code
Definition
The device is an indirect immunofluorescence assay utilizing monoclonal antibodies and flow cytometry in the quantitative determination of complement 4d (C4d) and complement receptor 1 (CR1) on the surface of erythrocytes from EDTA anti-coagulated whole blood. The C4d and CR1 results are used in a ratio as an aid in the diagnosis of systemic lupus erythematosus.

CFR § 866.5820 Systemic lupus erythematosus immunological test system

§ 866.5820 Systemic lupus erythematosus immunological test system.

(a) Identification. A systemic lupus erythematosus (SLE) immunological test system is a device that consists of the reagents used to measure by immunochemical techniques the autoimmune antibodies in serum and other body fluids that react with cellular nuclear double-stranded deoxyribonucleic acid (DNA) or other nuclear constituents that are specifically diagnostic of SLE. Measurement of nuclear double-stranded DNA antibodies aids in the diagnosis of SLE (a multisystem autoimmune disease in which tissues are attacked by the person's own antibodies).

(b) Classification. Class II (performance standards).
