SWAB INTRODUCTION

Stuart Transport Medium is a nonnutritional medium which maintains the viability of organisms without significant multiplication. The small agar content provides a semisolid consistency which prevents oxidation and drying during transport. Sodium thioglycollate is added to produce a reduced environment so as to improve the recovery of anaerobes. Methylene blue is the oxidation-reduction indicator. The medium appears colorless in the reduced state and blue in the oxidized state. Calcium chloride maintains permeability of bacterial cells and sodium glycerophosphate maintains the pH of the medium.

SWAB FEATURES

Ergonomic and anatomic design, perpendicular nylon fiber acts like a soft brush thus improves patient comfort an deficiency in cell specimen collection.

Improved sample collection, sprayed-on fibers statically charged and attached to the applicator tip in a uniform perpendicular manner and by means of strong capillary action cell specimens are rapidly absorbed.

Superior sample elution, with an open fiber structure it instantly dislodge s the specimen cells into the liquid medium, unlike traditional wound swabs when the specimen is entrapped in the mattress core.

Increased assay sensitivity, flocked swabs are proven to elute>95%of the original sample rapidly thus easily resulting in improved assay sensitivity.

Quantitative volume transfer, measurable and consistent uptake and transfer from patient to the test tube has no internal mattress core to disperse and entrap the precious sample like traditional fiber wound swabs.

 

Certified free of inhibitors and interference, collection swabs are certified DNASE, RNASE-free and human DNA-free.They are also free of any PCR inhibitors, certificate of analysis available for each lot of manufacture.
