You may have seen pus cells, an off-white fluid that secretes from the injured site, usually from a popped pimple. Excess pus from any incision or wound indicates you have suffered an infection, which your immune system is actively fighting. Simply put, it’s a sign your white blood cells have fought the infection successfully. Our immune system releases white blood cells to the target site if it notices a virus, bacteria, or any pathogen within your system. The pus color could also vary from off-white to yellowish to brown.

But what if these pus cells are found in urine? Is it normal? Or does it indicate an underlying medical condition?
