CULTURE AND SENSITIVITY Meaning and
Definition
-
Culture and sensitivity, commonly referred to as C&S, is a medical laboratory test that aims to identify and determine the susceptibility of a microorganism, such as bacteria or fungi, to a variety of antibiotics or antifungal agents. The term "culture" refers to the process of cultivating or growing an organism in a laboratory setting, while "sensitivity" refers to the subsequent testing of that organism's response to various drugs.
In this test, a sample is typically obtained from a patient's infected site or bodily fluid, such as blood, urine, or sputum. The sample is then incubated in the laboratory under specific conditions to encourage the growth of any potentially infectious microorganisms present. Once the microorganisms have multiplied, they can be identified, usually through microscopic examination or biochemical tests. This identification process is crucial in determining the most appropriate treatment for an infection.
After identification, the microorganisms are exposed to a range of antibiotics or antifungal drugs. By observing how they respond to these drugs, their susceptibility or resistance can be determined. This information helps guide healthcare professionals in choosing the most effective medication(s) for a particular infection, ensuring appropriate treatment and reducing the chances of resistance development.
Culture and sensitivity testing is an essential tool in healthcare for diagnosing and treating infections in a targeted and evidence-based manner. It helps optimize patient care by providing valuable information about the pathogens involved and their corresponding drug sensitivities, ultimately aiding in the selection of an appropriate antibiotic or antifungal therapy.
