What tests indicate disorders like lupus relative to arthritis?

ANSWER

The ANA profile is a series of tests that measure the presence of abnormal antibodies. The profile helps your doctor look for diseases such as Sjögren's syndrome, lupus, drug-induced lupus, polymyostitis, and scleroderma.

When the ANA is positive, it indicates that you may have an autoimmune disorder, but the test alone can't make a reliable diagnosis. If the ANA is negative, it is likely that you don't have lupus.
