What does the term 'purulent' refer to?

The term 'purulent' refers specifically to a substance that resembles pus. Pus is typically a thick fluid that is a result of the body’s inflammatory response to infection, comprised of living and dead white blood cells, bacteria, and tissue debris. When a urinalysis or any medical examination indicates that a fluid is purulent, it generally suggests that there is an underlying infection or inflammatory process taking place. This can often guide healthcare providers in determining the appropriate treatment for infections or other medical conditions. Understanding this term is essential for medical professionals, as it helps in identifying infections and planning further diagnostics or treatments.
