In brief: Depends on the lab.

There are different methods of measuring the ANA.
Often it may be read as a titer. A result less than 1:40 is negative. Often an ANA of 1:40, 1:80 and even up to 1:160 may be falsely positive.

In brief: Negative

Although it is not uncommon for healthy people to have low titer anas at 1:40-1:80 in a speckled pattern.

In brief: ANA

Normal reading negative.
Positive not necessarily disease state. Interpretation includes patient symptoms physical and laboratory.

In brief: Negative

A negative test is the normal.
I personally consider a titer of 1:80 to be borderline and a titer of 1:160 to be positive.
