A few questions help us personalize your report.
The ANA titer reports the strength of the antinuclear antibody signal, expressed as the highest dilution at which antibodies are still detectable. Higher titers (1:320 and above) are more likely to reflect true autoimmune disease, while low titers (1:40–1:80) are frequently seen in healthy individuals and carry less clinical significance. The titer alone doesn't diagnose any specific disease — it must be interpreted with the pattern and specific antibody subtests in the context of symptoms.
High ANA titers (1:320 or above) are more likely to indicate true autoimmune disease. Lower titers (1:40-1:80) are commonly found in healthy individuals without clinical significance.
Negative or below 1:40 is optimal. Titers of 1:160 or above warrant clinical correlation and specific antibody testing.
