A member asked:
If blood test by pcr was negative for hla b27, does this mean i definitely don't have it? (one other blood test was positive; not sure of the type).
A doctor has provided 1 answer
HLA B27: Indicates a genetic predisposition associated with ankylosing spondylitis and a number of inflammatory disorders. It does not mean you don't have whichever disorder you are referring to.
