ANA Blood Test (Antinuclear Antibody – Immunofluorescence)
Uncover hidden autoimmune activity behind persistent symptoms.
What’s tested
Pick a time
The ANA blood test detects antinuclear antibodies, autoantibodies that target components of your own cell nuclei. It is used to screen for autoimmune conditions when patients present with persistent symptoms such as joint pain, unexplained fatigue, skin rashes, or recurring fevers. It is also requested to support the investigation of suspected connective tissue diseases including lupus (SLE), Sjögren's syndrome, scleroderma, and mixed connective tissue disease.
The test is performed using immunofluorescence, a technique that visualises antibody binding to specific cellular structures. This method provides both a titre (how much antibody is present) and a pattern (which part of the cell is targeted), giving clinicians valuable clues about the underlying condition.
Biomarkers included
- Antinuclear antibody (ANA)
Why it matters
A positive ANA result can be the first indicator of an autoimmune process, guiding further targeted testing and specialist referral. Early detection supports timely management, helps prevent organ damage, and allows you to have a more informed conversation with your doctor about your symptoms and next steps.
No special fasting required. Drink plenty of water prior to your appointment for a smooth blood draw.
- Identification: Photo ID (Passport or Driving Licence) is only required if you need your report for official, employment, visa/travel, premarital, or Identity-Verified Certificate (IVS) purposes (not required for personal health & wellness testing).
This test provides an official, quality-assured laboratory report with reference ranges. These results are for clinical information and do not replace your GP or consultant. Always discuss abnormal results with your GP or specialist in the context of your medical history.
