Ok my test results came back from my ana titer test and the doctor said 1- 320 and that its borderline . whats this mean ?

Borderline ANA: All tests have a normal range of values. If a test value is at the upper limit of the normal range or slightly over, it's often referred to as "borderline." the importance of a borderline ANA test depends on the other criterion that are present. A borderline positive ANA will probably be ignored by the doctor if there are only one or two other criterion suggesting lupus.

See rheumatologist: First, that does not appear to be borderline. Second, see a rheumatologist.
