This field is used to report the presence of extraneous contaminating materials observed during the microscopic examination of the urine sediment.

Pollens, mold spores, glove powder, and fibers of various types are among the more common sorts of materials referred to by this section.

Generally, such material is significant only as an indication of the conditions of collection and/or handling of the specimen prior to analysis. Debris is more frequently seen in voided urine samples or those collected off the floor or from litter trays. On occasion, confusion may arise if these are mistaken for findings of significance (casts, parasites, etc.).
