Nothing vs. smth: First off, not sure why it was done. You must understand that in medicine it is not right to chase a positive test only. There may be symptoms also suggestive of a disease.

What does a positive result on the ANA titer mean?

Further testing: A positive ANA may not be significant. First of all why was the test done. If it was done for joint pain it will mean more then if a physiciab did one as a part of an annual physicial.
