What level of ANA indicates lupus?

The initial requirement of the criteria for lupus diagnosis is a positive ANA test with a titer of at least 80. The numerical value of the titer refers to the ratio of blood serum being evaluated to a dilution agent.

What is borderline lupus?

A doctor may use the phrase "borderline lupus" when symptoms or blood test results suggest lupus, but there is not enough information for a definite diagnosis.

Can you have a normal ESR with lupus?

A normal ESR is usually about 0-20 millimeters per hour in females and 0-12 millimeters per hour in males. The ESR is nonspecific, meaning that it does not tell your doctor exactly where the inflammation is occurring in your body and is thus not a very strong indicator of lupus activity.

What is a strongly positive ANA test?

A strongly positive ANA test means that it is more likely that a person has an autoimmune disease. However, positive test results do not tell what type of autoimmune disease it is.

Is a positive ANA test serious?

The presence of antinuclear antibodies is a positive test result. But having a positive result doesn't mean you have a disease. Many people with no disease have positive ANA tests — particularly women older than 65.
