Nieluviljelyä

Nieluviljelyä, also known as pharyngeal culture or throat swab, is a common diagnostic procedure used to detect the presence of microorganisms in the throat. This technique involves collecting a sample of mucus or secretions from the back of the throat using a sterile swab. The swab is then used to inoculate a culture medium in a laboratory setting. This medium provides a suitable environment for any bacteria or fungi present in the sample to grow and multiply.

The process of nieluviljelyä is typically straightforward. A healthcare professional will ask the patient to open their mouth wide and tilt their head back. The swab is then gently rubbed against the tonsils and the posterior pharyngeal wall, areas where infections are often located. The patient may experience a brief gagging sensation during the collection. It is important for the patient to remain still during the procedure to ensure an adequate and uncontaminated sample is obtained.

Once collected, the swab is transported to a laboratory. Technicians will streak the swab onto various culture plates containing different types of growth media. These plates are then incubated at specific temperatures and humidity levels for a period, usually 24 to 48 hours. During incubation, if pathogenic microorganisms are present, they will form visible colonies on the culture plates. Further tests may be performed on these colonies to identify the specific type of microorganism and determine its susceptibility to various antibiotics. This information is crucial for guiding appropriate treatment decisions for throat infections.
