I'm 49 years old female.
Two months ago i was diagnosed with cutaneus vasculitis (just on my legs) and my doctor send me to do some lab test. Blood test - normal, ANA - negative, antidsDNA - 88.8 IU/ml ( >55 IU/ml). So, i'am worried about this last result. Don't have any other symptom, except chronic nasal congestion and frequent muscle pain over my body that doesn't stop me from being daily active.
I wonder,whether it can be Lupus?
R Swamy Venuturupalli, MD, FACR responded:
Lupus is usually diagnosed using the American College of Rheumatology criteria. If a person has 4/11 criteria for lupus they meet the ACR classification criteria. These criteria contain both clinical features and laboratory features. Just having a positive test does not give you lupus and there are many instances of false positive lab tests. Please consult with a rheumatologist to determine if you have lupus. Please look over some of our previous posts regarding diagnosis. All the best.
