In those who are ANA-positive we suspect there are features that can help distinguish those who will later develop disease.Aim To understand the characteristics of those tested, and in those who have positive features associated with disease development.Method Two phase study: 1) A case control ...
For the ANA test, 1 part of the serum is diluted into 40 parts of diluent (called a “1:40” titre). This diluted sample is tested for the presence of ANA antibodies. If the test is positive, a new sample is made at half the strength (1:80) and tested for the presence of ANA...
the line that sepa-rates“positive”results from“negative.”If the clinician does not know the sensitivity and specificity of the test kit used, the positive or negative predictive value of the test is difficult to assess,and one must be careful in applying the results to guide patient care....
