ANA (Autoimmune) Test
Screens for antibodies linked to autoimmune conditions such as lupus — a key first step in autoimmune assessment.
The ANA test screens for antibodies linked to autoimmune conditions such as lupus, serving as a key first step when an autoimmune disorder is suspected.
About the ANA (Autoimmune) Test
This blood test detects Antinuclear Antibodies (ANA), which the immune system may produce when it mistakenly targets the body’s own cells. A positive ANA can support the investigation of autoimmune conditions such as lupus and related disorders. Because a positive result can also occur in healthy people, ANA is interpreted by a doctor alongside your symptoms and, often, more specific follow-up tests.
Preparation and turnaround
A quick venous blood sample is taken with no fasting required. Results are usually available within one to two working days. A positive ANA usually prompts further, more specific testing, and results are best reviewed with a doctor in the context of your symptoms.
