Im a 19 year old male. Ive had back pain for three months now, and blood tests from my PCP came back with high sed rate, high CRP, and positive for HLA-B27. My family has no history with Ankylosing Spondylitis, but Im terrified I have it. Help?
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).
Few cases of iritis. Had hla-b27 blood test done. One was positive, one was negative (by pcr). Since PCR is most sensitive, does this mean i'm clear?
Had 2 blood tests for hla b27. 1st test came back positive; 2nd test (pcr) came back negative. What would be the difference between the two tests?
For blood test for hla b27 -- what is the difference between the standard test and the PCR blood test?
