Artifacts

Artifacts are substances observed under a microscope that are found in urine through accidental contamination. They are of no clinical interest. Some of the most common artifacts include glass debris, air bubbles, fabric fibres and human or animal hair. With the more widespread use of latex gloves, starch crystals or talcum powder can also be found.

Term of the Week

Hot zone

A hot zone is a section of a facility (sometimes an entire facility or even a city district) where there is a high risk of contamination by patients with an infectious disease. All individuals entering a hot zone must respect appropriate protective measures. By analogy, “cold zone” and “warm zone” are used to refer to areas where there is no infected individual or only individuals suspected of having an infection.
