In the same study, 38.5% of patients with noninflammatory âsoft tissue rheumatismâ had a positive ANA result. at a 1:40 dilution, and 23.1% at a 1:80 dilution. Slater et al (6) studied 1,010 consecutive ANA results at a teaching hospital and attempted to correlate the results with clinical histories by chart review.
