Understanding Your Results
Negative (< 1:10 dilution)
No significant anti-dsDNA antibodies detected; may indicate absence of active autoimmune disease.
Action: Consult physician if symptoms persist; consider other diagnostic tests.
Positive (≥ 1:10 dilution)
Elevated anti-dsDNA antibodies, suggestive of autoimmune conditions like lupus. Higher titers correlate with increased disease activity.
Action: Immediate consultation with a rheumatologist or immunologist for further evaluation and management.
If you experience symptoms such as persistent fatigue, joint pain, skin rashes, or if your test results are positive, consult a healthcare provider promptly for a comprehensive assessment and personalized treatment plan.
