System Lupus Erythematosus is diagnosed based on the presence of multiple
standard criteria - only one of which is the ds-DNA.
There is NOT one single definitive test for Lupus -- you must match 4 or more of 11 symptoms, and even then it may be another similar auto-immune disease. See the link Diagnosing Lupus below.
