[|Human|] I have recently had lab work for lupus , I received lab results back with no explanation. ANA profile; ana= 24 (0-100AU/ml); ssa 8( 100 AU/ml); ssb= 6 ( 100 AU/ml); sm= 9( 100 AU/ml); RNP =22( 100 AU/ml); SCI-70 =24( 100 AU/ml); JO-1= 8 ( 100 AU/ml); DSDNA = 0( 100 AU/ml);CENT B = 3( 100 AU/ml); HISTONE = 7( 100 AU/ml); Rheumatoid factor 50.1 ( 6.0 IU/ml)A Can someone please tell me does this mean that my ANA was positive or not in normal range. and if this anything to be concerned about. I am thinking not since the doctor just mailed the pages with nothing stating if I needed a follow up or if there is nothing to worry about and the pages are for my records.
[|AI|]  Hello, 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 quantitative 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 SHE) are very low. Obviously this test (if positive) is just one of 11 criteria for SHE, 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. Thanks.
