swabbprov

Swabbprov is a term used in some languages, notably Swedish, for a swab specimen collected for laboratory analysis. It covers samples obtained with a sterile swab from sites such as the nasal cavity, throat, wounds, or mucosal surfaces, as well as vaginal, rectal, or environmental swabs.

Collection and handling: Specimens are collected by trained personnel with sterile swabs, aiming to maximize sample adequacy and minimize contamination. After collection, the swab is placed in an appropriate transport medium, labeled, and kept under recommended temperatures until analysis.

Laboratory processing: In the laboratory, nucleic acids may be extracted and tested by PCR or sequencing, or the sample may be cultured or analyzed by rapid antigen tests. The assay chosen depends on the suspected pathogen and the required turnaround time.

Applications and limitations: Swab specimens are used for diagnosing respiratory infections, sexually transmitted infections, wound infections, and for various research applications. Their diagnostic value depends on the sampling site, timing relative to infection onset, and sample quality. False negatives can occur due to poor collection, delays in transport, or low pathogen load. Proper biosafety practices are essential when handling infectious material.
