Extending the Ontological Model for Urinary Profiles

Urinalysis (i.e. laboratory test of urine) provides information about patient’s health conditions based on the contents present in a urine sample. A key factor to guarantee the quality of the test, it is arranging urinary findings in a clinical context. Aiming to support the task, it was proposed an ontological model for Urinary Profiles (i.e. recurrent characteristics of urine that help in contextualizing it). Besides providing context, it allows predicting which contents should be observed in a sample based on what was already found in it. Although useful, such model defines Urinary Profiles as strictly related to the contents of the urine, when, in fact, it seems to be based on a broader context, including intrinsic properties of urine (e.g. pH) and things outside it (e.g. the patient from which the sample was collected). Thus, this paper proposes an extension to such model including other aspects of the urinary context. It is defined using the Unified Foundational Ontology (UFO).
