- INTENDED USE
SwabCollect™ Cary Blair with Charcoal, 5mL is used for transportation and preservation of microbiological specimen.
- PRINCIPLES
SwabCollect™ Cary Blair with Charcoal, 5 mL is used for collection and transport of clinical specimens. It is also recommended for transport of specimens. Since this transport media has a high pH, viability of Vibrio cultures can be maintained for a longer duration. This medium also facilitates the recovery of Salmonella and Shigella species.
Medium Base is prepared with minimal nutrients to facilitate survival of organisms without multiplication. Charcoal helps to neutralize materials that are toxic to sensitive pathogens like Neisseria gonorrhoeae. Sodium thioglycollate provides a low oxidation-reduction potential. Alkaline pH of the medium minimizes bacterial destruction due to the formation of acid. Disodium hydrogen phosphate buffers the medium whereas sodium chloride maintains the osmotic equilibrium.
- Peel open the sterile pouch at the point marked.
- Remove cap from transport tube.
- Remove applicator swab and collect specimen. During specimen collection, the applicator tip should only touch the area where the infection is suspected to minimize potential contamination.
- Place applicator swab in transport tube and replace cap firmly to completely seal.
- Record patient’s name and information on tube label.
- Send specimen to the laboratory for immediate analysis.
- Precaution: When collecting swab samples from patients, care should be taken not to use excessive force or pressure which may result in breakage of the swab shaft.
- SwabCollect™ Cary Blair with Charcoal, 5 mL is produced in a closed environment, adhering to strict hygiene regulations. The plastic tube and swab are sterilized using EO gas, ensuring no microorganisms affect the quality of the sample.
BacterLab ensures the quality of each product batch of the medium by testing with ATCC reference strains.
Reference strains | Incubation conditions | Expected results |
Escherichia coli ATCC 25922 | 35 – 37°C for 18 – 24 hours | Good growth |
Neisseria meningitidis ATCC 13090 | Good growth | |
Salmonella Typhimurium ATCC 14028 | Good growth | |
Shigella flexneri ATCC 12022 | Good growth |
