C/S SPUTUM C/S

A sputum culture, a vital diagnostic examination, investigates the presence of bacteria or other organisms that might be causing infections within the lungs or airways. Unlike saliva, sputum—also known as phlegm—is a dense secretion formed within the lungs. Its production often accompanies infections or chronic conditions affecting these respiratory pathways, leading to coughing as a means of expelling it. Abundant in immune cells, sputum acts as a defense mechanism against invasive agents such as bacteria or fungi. Its thick consistency serves as a trap, capturing foreign substances and allowing microscopic cilia in the airways to move it upwards for expulsion through coughing. This intricate process aids in clearing potential threats from the respiratory system.
