Final answer:
Artifacts in urine such as mucous threads and starch granules are generally not quantified or reported because they do not hold clinical significance for diagnoses.
Step-by-step explanation:
In general, artifacts in urine sediment such as mucous threads and starch granules are not quantified and reported. This statement is false. In urine sediment microscopy, clinically significant findings like proteins, red blood cells, white blood cells, bacteria, cellular casts, and crystals are what are usually quantified and reported. Artifacts like mucous threads and starch granules may be noted, but they are not typically quantified as they do not usually hold clinical significance. However, if high amounts of such artifacts are present, it may indicate an issue with the urine sample collection or handling rather than a direct clinical finding relating to the patient's health.
