What are the normal ranges for the ANA tests,
especially the speckled pattern?
Antinuclear antibodies (ANAs) are most commonly described in titers of dilution. That is, the highest dilution at which they remain detectable. Normally, ANAs are described as Negative when they are less than or equal to 1:40 dilution.
For more information, please visit the MedicineNet.com article "Antinuclear Antibody Test."
Thank you for your question.
