The Lupus Profile II measures the presence of LE cells, complement C-3, complement C-4, hemolytic complement 50% (CH50), and anti-DNA antibodies in the blood, which is essential for diagnosing and monitoring systemic lupus erythematosus. We use Chemiluminescence (CMIA), Immunoturbidimetry, Microscopy, and Enzyme Immunoassay (EIA) techniques to ensure accurate and reliable results.
