Anti Nuclear Antibody (ANA) is the screening test for autoimmune disease — conditions where the immune system mistakenly attacks the body's own tissues. It is usually among the first tests a physician orders when symptoms wander across systems: joint pains plus a rash, fatigue plus hair loss, dry eyes plus finger swelling.
A positive ANA opens the differential diagnosis for conditions like lupus (SLE), Sjögren's syndrome, scleroderma and related disorders. It is a screening marker, not a diagnosis on its own — many healthy people have weakly positive ANA, which is why doctors interpret the titre and pattern together with your symptoms, and may follow with more specific antibody tests.
The test is a single home blood draw with no preparation needed, processed at an NABL-grade partner laboratory, with a detailed report in your app for your rheumatologist or physician.
No. ANA is a screening marker — positive results occur in lupus and related autoimmune diseases, but also in some healthy people. Diagnosis depends on your full symptom picture and follow-up tests.
