Test Code

The ANA (Anti Nuclear Antibodies) – IFA test is a highly sensitive screening assay used to identify autoimmune activity in the body. It is performed using the Indirect Fluorescent Antibody (IFA) technique on HEp-2 cells, which is considered the gold standard for ANA testing.
This method not only determines whether ANA is present but also reports antibody titers and fluorescence patterns (homogeneous, speckled, nucleolar, centromere, etc.), which provide valuable clues toward specific autoimmune conditions.
A positive ANA result does not confirm a disease on its own but helps clinicians decide further specific antibody testing and correlate findings with clinical symptoms.

Frequently Asked Questions

It is used to screen and support diagnosis of autoimmune diseases such as SLE, scleroderma, and Sjögren’s syndrome.

IFA is more sensitive and provides antibody titers and staining patterns, offering better diagnostic insight.

Not always. Some healthy individuals may have low-titer positive ANA; results must be interpreted with symptoms.

No fasting is required.

Common patterns include homogeneous, speckled, nucleolar, and centromere, each linked to specific conditions.

Yes. Some autoimmune diseases may still be ANA-negative, especially in early stages.
