Understanding Your Results

Interpretation of Jo-1 Antibody Test results requires a qualified healthcare provider. A positive result indicates the presence of Jo-1 antibodies, which are associated with specific autoimmune disorders, while a negative result may not entirely rule out such conditions if symptoms persist.
📊

Positive

Presence of Jo-1 antibodies, strongly associated with polymyositis and interstitial lung disease. Further evaluation with additional tests is recommended.

📊

Negative

No detectable Jo-1 antibodies. However, it does not completely exclude autoimmune myositis; correlation with clinical symptoms and other diagnostic tests is advised.

⚠️ When to Consult a Doctor:

If you experience symptoms such as unexplained muscle weakness, persistent fatigue, fever, joint pain, or breathing difficulties, consult a rheumatologist or immunologist for evaluation and potential testing.
