Patient's question:
My father-in-law has been in poor health for a long time. Today, I took him for a thorough examination, and the doctor said he has ankylosing spondylitis. Blood tests are definitely one of the necessary tests. The detailed examination results were negative. I don't understand the difference between negative and positive. Is there any difference? How is a strong positive ankylosing spondylitis better than a positive one?Doctor's answer:
Seronegative ankylosing spondylitis is generally more severe and harder to treat than seropositive cases. Of course, treatment is primarily based on individual symptoms, as it is not fixed for everyone. Seronegative simply means that 40% of people with ankylosing spondylitis test negative. Generally, it is controlled through corticosteroids or immunomodulatory drugs.
