Blood Tests for Lupus

No single test can diagnose lupus. A combination of blood tests, clinical examination, and patient history is necessary for a diagnosis.

When you test positive on an ANA test, it suggests an autoimmune process. It is common in lupus but can occur in other autoimmune diseases and some healthy individuals.

Certain tests, like complement levels and anti-dsDNA, may help predict flares by indicating increased disease activity.
