Screen: ANA Panel (Quest)

What this panel includes

• ANA screen (IFA method): Detects the presence of antinuclear antibodies, a common early indicator of autoimmune activity

• Reflex to titer: If antibodies are detected, the lab automatically measures their concentration (titer) to assess the strength of the immune response

• Reflex to pattern: Identifies the staining pattern of the antibodies, which can help point toward the specific type of autoimmune condition involved

Biomarkers tested

Why patients choose this

• A first step in understanding whether autoimmune activity may be present, by checking for antinuclear antibodies.
• Helpful for those with unexplained joint pain, fatigue, rashes, or hair loss.
• Includes automatic reflex to titer and pattern, so a positive result comes with the added detail clinicians use to guide next steps.
• Appropriate for those with a family history of autoimmune disease or symptoms suggestive of autoimmune involvement.
• Schedule your lab test seamlessly and complete it at a lab near you.

Before your test

It is recommended to fast for at least 8 hours before.

Important information

Why it matters: ANA can be a common early finding in autoimmune conditions such as lupus, Sjögren's syndrome, scleroderma, and rheumatoid arthritis, and can help guide whether further evaluation is needed.

Who it's for: appropriate for those with unexplained joint pain, fatigue, rashes, or hair loss, or a family history of autoimmune disease.

It checks for the presence of autoimmune activity but does not diagnose any specific condition; results are interpreted by a clinician alongside your symptoms and history.

It is recommended to fast for at least 8 hours before.
