Can you have ankylosing spondylitis with a negative HLA-B27?
However, nearly 10–20% of patients with defined AS do not carry HLA-B27, which increases to 40% when analyzing nonradiographic axial spondyloarthritis (nrAxSpA) [5]. Previous studies suggest a relationship between HLA-B27 and axial manifestations including structural progression in early AxSpA [5].3 oct. 2018What if my HLA-B27 is negative?
A negative result means you don't have HLA-B27 in your blood. A positive result means HLA-B27 was found in your blood. You may have a higher-than-average risk of certain autoimmune diseases, such as ankylosing spondylitis and reactive arthritis.Can HLA-B27 change from negative to positive?
Serological typing with the microlymphocytotoxicity test (MLCT) and flow cytometry (FC) using HLA-B27 antisera is commonly used for the determination of HLA-B27. However, in some patients tested more than once, negative results have turned out to be positive at following investigations.- In patients suffering from ankylosing spondylitis (AS) HLA-B27 determination by means of the microlymphocytotoxicity test (MLCT) sometimes gives equivocal or false-negative results even though it has been performed with meticulous care.
