Swabs are an invaluable tool employed in medical diagnostics that enables collecting biological samples from various parts of the body. They are crucial in microbiological studies and key in diagnosing and monitoring diseases. Learn about their ins and outs, and the role they play in the medical industry.
Swab design and types
Swabs are specialist tools for collecting biological samples from the surface of mucous membranes, skin or other tissues. They consist of a shaft and a tip that may be made of various materials, such as cotton, polyester or fibreglass. Selecting the right swab type from the models offered by manufacturers of laboratory products is critical in terms of obtaining reliable test results. The sterility of the tool and its compatibility with the analysed biological material are significant aspects to pay attention to.
Collecting biological samples with swabs
The application of swabs is extremely broad and covers numerous medical fields. For example, swabs employed during microbiological studies enables collecting samples from the mouth, nasopharynx, genital tract or the urinary tract. Dermatologists use them for diagnosing such skin diseases as mycoses or impetigos. Swabs are also essential in oncological research, wherein they are employed in collecting cell samples for cytological analysis. When collecting samples, it is crucial to follow aseptic principles and avoid material contamination.
Analysing biological samples collected using swabs
Biological samples collected with swabs are then analysed in diagnostic laboratories. Examination types include microscopic tests, bacterial cultures, genetic testing or biochemical analysis. Samples can also be stored under appropriate conditions for analysis in the future. Precise and accurate material collection with swabs offered by NOEX, a manufacturer of plastic products, enables obtaining reliable test results that are critical for further patient treatment.
The role of swabs in tackling the COVID-19 pandemic
Swabs played a crucial role in tackling the COVID-19 pandemic. They were used to collect samples from the nasopharynx of the patients, which were then analysed for the presence of the SARS-CoV2 virus. Identifying the infection at an early stage enabled isolating a patient and monitoring the patient’s health, which was key for limiting virus spread.
