After several weeks of testing, the BD Diagnostic TestsSalmonella H Antiserum b to Vibrio Cholerae Antiserum, BD Diagnostics 222691 Salmonella H Antiserum G Complex continued to perform reliably. Its consistency across multiple tests gave confidence in the results, reducing the need for repeat testing. Minimal reagent is required per test, limiting wastage.
The antiserum showed no signs of degradation, even under varying temperature conditions (within recommended storage parameters, of course), making it suitable for deployment to remote areas. Its performance consistently outperformed older, less refined serological methods.
Breaking Down the Features of BD Diagnostic TestsSalmonella H Antiserum b to Vibrio Cholerae Antiserum, BD Diagnostics 222691 Salmonella H Antiserum G Complex
Specifications
- Description: Salmonella H Antiserum G Complex. This antiserum specifically targets the H antigen G complex of Salmonella, crucial for accurate serotyping.
- Size: 3 mL. The 3mL volume is sufficient for numerous tests, assuming proper handling and minimal wastage.
- BD No.: 222691. This is the unique identifier for the product, ensuring correct ordering and traceability.
These specifications are vital because accurate identification of Salmonella serotypes is crucial for tracking outbreaks and implementing effective control measures. The specificity of the G complex antiserum ensures fewer false positives, while the volume provides ample reagent for routine testing.
Performance & Functionality
The BD Diagnostic TestsSalmonella H Antiserum b to Vibrio Cholerae Antiserum, BD Diagnostics 222691 Salmonella H Antiserum G Complex excels in providing rapid, presumptive identification of Salmonella isolates. Agglutination occurs quickly and is easily visible, even to the untrained eye. Minimal cross-reactivity with other bacterial species was observed.
However, it’s essential to remember that this is a presumptive test. Confirmation requires further biochemical and serological testing. This is not a replacement for comprehensive laboratory analysis.
Design & Ergonomics
The small vial design is practical for field use and storage. The labeling is clear and concise, preventing confusion.
The reagent itself is easy to handle, though proper aseptic technique is critical to avoid contamination. The vial could be improved by providing a dropper tip to control reagent dispensing more accurately.
Durability & Maintenance
The product’s durability hinges on proper storage. Refrigeration is mandatory to maintain potency.
The antiserum requires minimal maintenance beyond ensuring vials are sealed properly to prevent evaporation and contamination. Periodic checks of the expiration date are vital.
Accessories and Customization Options
The BD Diagnostic TestsSalmonella H Antiserum b to Vibrio Cholerae Antiserum, BD Diagnostics 222691 Salmonella H Antiserum G Complex comes as a standalone reagent. It’s designed to integrate seamlessly with standard microbiology lab equipment. It can be used in conjunction with other Salmonella antisera for comprehensive serotyping.
There are no specific customization options, however its utility is greatly enhanced by use of proper bacteriological loops, adequate lighting and sterile saline for bacterial dilution. The results can also be customized depending on whether the agglutination is graded on a subjective scale (e.g., 1+ to 4+).
