Please help,
I just received my blood panel and my SM was 103.0mL and the reference range is 0-89. I know this is for lupus and I'm very concerned since I'm over the safe range. All my other test came in normal but this one has me nervous. I can't find anything on the web for this SM blood panel reference guide.

R Swamy Venuturupalli, MD, FACR responded:
Anti-smith antibody is a specific auto-antibody for lupus and when present in high titres, could be associated with lupus kidney disease. In your case the titre is low, and I am not sure of the rest of your medical history. Just having this test does not make it certain that you have lupus and it needs to be looked at in the context of your other symptoms and blood tests. Please look at our previous posts on the topic of how to diagnose lupus.

Please let me know if you have any follow up questions.
