360 Degree Jet Flocked Swab Nylon Head Sampling
There's no adhesive residue to intervene with amassing cells for DNA checks, forensic proof or other uses. Flocking is multi-size fibers applied to an adhesive-coated surface.
Based on these standards, RT-PCR, DFA, and culture, usually performed with secretions from the posterior NP, usually are not perfect for use within the ED because check complexity requires that these assays be performed in the primary laboratory, and the turnaround time is usually prolonged. In distinction, fast antigen testing carried out at the point of care or in the principle laboratory on specimens obtained from the AN is a extra well timed choice for clinicians and extra comfortable for patients.
An enhanced diagnostic yield could also be potential if swab types that capture a higher load of virus-contaminated cells are utilized. This study in contrast the detection of influenza virus from secretions from the AN in a rapid antigen test when specimens have been collected with polyurethane foam swabs to detection when specimens had been collected with flocked nylon swabs. Utilizing RT-PCR positivity of NP specimens as a gold standard, we discovered a better performance with foam swabs than with flocked swabs. A comparable trend was noted when DFA and/or tradition positivity was used as our gold commonplace; nevertheless, this development didn't attain significance. These variations had been strong when information were additional analyzed by sort of influenza but again failed to reach significance due to smaller sample sizes per influenza type.
Rapid antigen testing is understood to have a lower sensitivity for influenza B virus than for influenza A virus, and this trend was additionally current in our study whatever the swab sort and gold commonplace used . Puritan HydraFlock swabs engineered for the collection and launch of biological specimens. Uses polyester tip that's designed to reinforce rapid absorption and launch of specimens. Puritan's trademarked HydraFlock flocked swabs have velvety brush suggestions and multi-length fibers. This allows the swab to raised take in release collected specimens.
Our proprietary manufacturing course of provides swabs with multi-length flock fibers providing you with essentially the most efficient assortment and elution available on the market. An ideal laboratory check for diagnosing influenza virus infection within the ED would combine ease of collection and tolerability with accuracy and timeliness for determination making.
Puritan is the one flock swab manufacturer which holds patents for our HydraFlock® and PurFlock Ultra® collection devices. We’re not the only ones to offer flocked swabs, but we’re the only firm with a patented specimen assortment manufacturing process.
