A swab test, also known as a swab culture or specimen collection, is a diagnostic procedure involving the use of a swab to collect samples from the body. These samples are analyzed in a laboratory to detect microorganisms, genetic material, or other substances. Swab tests have various applications, including diagnosing infections, genetic testing, forensic analysis, microbiological research, STI screening, and wound culture. The choice of swab and collection site depends on the specific diagnostic purpose. Swab tests play a vital role in medicine, diagnostics, and research, contributing to public health, forensic investigations, and scientific discovery.
