Drug-induced chronic cutaneous LE is the rarest of the three forms. The sensitivity and specificity of a positive ANA result are 48% and 52%, respectively; the LR+ is 0.99, and the LR is 1.01.11, Sjgren antibodies may also be present when the syndrome develops in patients with other connective tissue disorders. Its pooled sensitivity and specificity are 67% and 95%, respectively; the LR+ is 12.46, and the LR is 0.36.26, Positive anticyclic citrullinated peptide antibody titers may provide information about prognosis and the likelihood of developing erosive disease.27 However, serial monitoring of these titers is not recommended because variations do not correlate with response to therapy.26.

Myositis-specific antibodies are present in only about 20% of patients with this syndrome.21 Anti-Jo-1 antibodies are directed against histidyl-transfer RNA synthetase and comprise 80% of the myositis-specific antibodies in antisynthetase syndrome.21 Because of their low prevalence, these antibodies should not be measured routinely in patients with myalgias. Do not test ANA subserologies without a positive ANA test result and clinical suspicion of immune-mediated disease. Many times, a positive ANA screening test will also come with a titer.. For this test, we use a specific type of cell called HEp-2. If, under their physicians approval, the person can be off the medicine for that length of time, a negative test should result.. I will give you just a few examples : Rarely a positive ANA can be seen in patients with a history of cancers like lymphoma or other solid organ cancers.
