According to the ASAS axial SpA criteria patients with chronic back pain aged less than 45 years at onset can be classified as having axial SpA if sacroiliitis on imaging radiographs or MRI plus 1 further SpA feature are present or if HLA-B27 plus 2 further SpA features are present.
May be used in conjunction with ASAS Criteria for Axial SpA use.

In the present work the Assessment in SpondyloArthritis international Society ASAS provides a comprehensive handbook on the most relevant aspects for the assessments of spondyloarthritis covering classification criteria MRI and x rays for sacroiliac joints and the spine a complete set of all measurements relevant for clinical trials and international recommendations for the management of SpA.

To some experts referred to as lump-ers this is appropriate because they consider different SpA entities as variable expression of the major features of the same disease.
The primary entry criterion is current arthritis enthesitis or dactylitis at clinical examination without current back pain. In the entire ASAS population of 975 patients the combined use of ASAS criteria for axial SpA and ASAS criteria for peripheral SpA also had a better balance sensitivity 795 specificity 833 than the modified ESSG sensitivity 791 specificity 688 and Amor criteria sensitivity 675 specificity 867 respectively. The ASAS criteria classified 81 of all patients n 581 as having either axial SpA 44 or peripheral SpA 37 whereas a lower proportion met ESSG criteria 74 and Amor criteria.
