ANA Titer
ANA titer reports the highest dilution of serum at which antinuclear antibodies are still detectable and quantifies the strength of a positive ANA. Higher titers (for example 1:320 or greater) are more likely to reflect true autoimmune disease, while low titers (1:40 to 1:80) can occur in healthy people. Titer is interpreted alongside pattern and specific autoantibodies.

What is ANA Titer?
ANA titer reports the highest dilution of serum at which antinuclear antibodies are still detectable and quantifies the strength of a positive ANA. Higher titers (for example 1:320 or greater) are more likely to reflect true autoimmune disease, while low titers (1:40 to 1:80) can occur in healthy people. Titer is interpreted alongside pattern and specific autoantibodies.
Why It Matters
Quantifies ANA concentration. Higher titers more strongly associated with autoimmune disease. Pattern and titer guide further testing.
