Ankylosing Spondylitis (AS) is a chronic inflammatory 
systemic disease belonging to the SpondyloArthritidies with axial 
joint involvement and enthesitis, with or without peripheral 
arthritis and systemic involvement. 
We know that the clinical/paraclinical judgement of an 
expert Rheumatologist is the gold standard for diagnosis of AS. 
It is mentioned that the 1984 modified New York criteria 
is applied for classification of AS and it is not a good instrument 
for early detection of disease. 
The author by this letter delivers a new criteria called 
2016 New York revised criteria that is applied for too early 
diagnosis of AS. 
With the addition of pelvic MRI, HLA-B27 positivity, 
positive family history of AS, Enthesitis/arthritis and positive 
sacral push test to the 1984 modified New York criteria and 
deletion of limited chest expansion from it, this new criteria has 
been created.
