Viewer Question:I have had 90% of the symptoms that go along with lupus. Please let me know when someone is ANA negative, but still has lupus. My ANA tests were 1:40 and 1:60. I've been tested for a few antibodies, and so far nothing shows positive. How can someone have lupus and be negative ANA?
Doctor's Response:When a person satisfies the criteria for systemic lupus erythematosus (lupus), but has a negative ANA, the condition is referred to as ANA-negative systemic lupus erythematosus. ANAs are negative in approximately 5% of patients with lupus. In these patients, frequently there are other antibody markers of lupus present, such as cardiolipin antibody, anti-smith antibody, DNA antibodies, and SS-A and SS-B antibodies.
Thank you for your question.
