Detection methods refer to various techniques used to identify the presence of specific substances, organisms, or conditions. These methods can include physical, chemical, or biological approaches, such as using sensors, reagents, or assays. Common applications range from environmental monitoring to medical diagnostics, where accurate detection is crucial for effective decision-making. In the field of medicine, detection methods are vital for diagnosing diseases. Techniques like PCR (Polymerase Chain Reaction) amplify DNA to identify pathogens, while immunoassays use antibodies to detect proteins. Each method has its strengths and limitations, making the choice of detection method important based on the specific context and requirements.
