FAQs
What are common reasons for being misdiagnosed with lupus?
Lupus symptoms overlap with many other conditions and the commonly used antinuclear antibody (ANA) test is highly sensitive but not very specific. Symptoms that come and go also add confusion, leading to misdiagnosis with diseases like rheumatoid arthritis, dermatomyositis, or chronic fatigue syndrome.
Which illnesses are most often mistaken for lupus?
Conditions commonly confused with lupus include rheumatoid arthritis, scleroderma, Sjögren's syndrome, fibromyalgia, dermatomyositis, rosacea, chronic fatigue syndrome, and Lyme disease.
How can I tell if my lupus diagnosis might be incorrect?
Question your diagnosis if lab results are repeatedly negative despite symptoms, if you don't experience typical lupus flares on medication, or if symptoms improve without treatment. Also, ask your doctor about specific criteria used for your diagnosis and consider getting a second opinion.
What steps should I take after suspecting a lupus misdiagnosis?
Request a thorough reevaluation including repeat ANA, anti-dsDNA, complement testing, and possibly skin or muscle biopsies. Seek a specialist’s opinion, consider legal advice if harmed by incorrect treatment, and find emotional support from patient groups.
How do treatments differ between lupus and conditions it mimics?
Lupus is often treated with hydroxychloroquine and steroids, while rheumatoid arthritis may require methotrexate or biologics. Accurate diagnosis ensures appropriate medication and avoids unnecessary side effects or delayed improvement.
