The test that you had was an ANA ELISA
that is being done in many laboratories replacing the ANA slide test that gives you a qualititative report (i.e., positive or negative). The ANA ELISA test gives you a number for an answer and the normal range is given in brackets next to it. All these test results show that specific autoantibodies are absent in your blood and therefore the chances of an autoimmune or connective tissue
disease (like SLE) are very low. Obviously this test (if positive) is just one of 11 criteria for SLE, so you need to ask your doctor why he did the test.
The low positive rheumatoid factor
is non-specific and the more specific test for rheumatoid arthritis
is the anti-CCP antibody test.
