I wanted to revisit this discussion on ANA pattern reporting. We also deal with testing labs where they pre-coordinate the pattern result into the test name and perform a call of whether the pattern is observed or not. For example, the 'test' the lab performs evaluates each staining pattern as listed below:

Then, the result for each of these tests is 'POSITIVE' or 'NEGATIVE', affirming presence or identity of the specific pattern in question.

For modeling pre-specified finding in MB, the approach has been:

• When asking an open-ended “what bug do you have in the culture” question,  MBTEST = Microbial Organism Identification; MBORRES = Name of the Microorg (from the Microorg codelist).
• When asking for a pre-specified finding “do you have this particular named bug in the culture” type question, MBTEST = Name of the specific Microorg, MBORRES = positive/negative, present/absent.

The MB example is to illustrate that the result of an open-ended question becomes the test or a test qualifier for the pre-specified findings question. This modeling principle applies consistently in IS as well.
