Ankylosing spondylitis (AS) is a chronic, inflammatory form of arthritis that mainly affects the spine. While there is no single test to diagnose AS, it is possible to have the condition and test negative for it.
Testing for Ankylosing Spondylitis
When looking for signs of AS, doctors will often look for clinical symptoms, which can include pain, stiffness, and fatigue. They may also order tests, such as X-rays, CT scans, and blood tests, to check for signs of inflammation.
However, it is possible to have AS and still test negative for it. This can be due to the fact that the tests used to diagnose AS are not 100% accurate, and can produce false negative results. This means that a person could have the condition and still test negative.
Diagnosing Ankylosing Spondylitis
If a person is showing clinical symptoms of AS, but tests negative for it, the doctor may still diagnose the condition if other factors are present. These factors can include family history, age, gender, and a history of previous medical conditions.
The doctor may also order other tests, such as an MRI or ultrasound, to get a better look at the spine and other joints. They may also request further blood tests to check for other markers associated with AS.
Living with Ankylosing Spondylitis
If a person is diagnosed with AS, they will likely be prescribed medication to help treat the symptoms. These can include anti-inflammatory drugs, such as ibuprofen, and other medications to help reduce pain and inflammation.
Exercise is also important for people with AS, as it helps to keep the joints and spine flexible and strong. It's also important to get enough sleep and rest, as fatigue can be a symptom of AS.
In conclusion, it is possible to test negative for AS and still have the condition. If someone is showing clinical symptoms of AS, but tests negative for it, the doctor may still diagnose the condition by looking for other factors and ordering other tests. If diagnosed, the treatment will likely involve medication and exercise.
