Pro-Lab Prolex™ Blue Staph Latex Kit for 100 tests

The Prolex™ Blue Staph Latex Kit is a rapid latex agglutination test designed for the detection of Staphylococcus aureus. It is widely used in clinical microbiology laboratories to differentiate S. aureus from other staphylococcal species by detecting protein A and clumping factor, which are unique to S. aureus. The kit's accuracy, ease of use, and rapid results make it a valuable tool in diagnostic workflows.

Key Features

1. Rapid Identification:
   • Provides results in under 1 minute, making it an efficient tool for busy laboratories.
2. Specificity:
   • Detects protein A and clumping factor, key markers for identifying S. aureus.
3. Ease of Use:
   • Simple latex agglutination test format requires no additional equipment or complex procedures.
4. Blue Latex Particles:
   • The kit utilizes blue-colored latex particles that visibly agglutinate in the presence of S. aureus, ensuring clear and unambiguous results.
5. Wide Applicability:
   • Can be used directly on bacterial colonies from culture plates, including blood agar or selective media.
6. High Sensitivity and Specificity:
   • Reliable results for differentiating S. aureus from coagulase-negative staphylococci.
7. Comprehensive Kit:
   • Contains all necessary reagents for up to 100 tests.

Kit Components

1. Blue Latex Reagent:
   • Coated with fibrinogen and IgG to bind clumping factor and protein A, respectively.
2. Negative Control Latex Reagent:
   • Ensures accurate interpretation of agglutination results.
3. Reaction Cards:
   • Used for performing and observing the test.
4. Mixing Sticks:
   • For mixing the latex reagent with the bacterial sample.
5. Instruction Manual:
   • Provides detailed step-by-step guidance for performing the test.

Testing Procedure

1. Preparation:
   • Ensure all reagents are at room temperature before testing.
2. Sample Collection:
   • Pick a single colony of the suspected staphylococcal isolate from an agar plate using a sterile loop or stick.
3. Test Setup:
   • Place a drop of the Blue Latex Reagent onto the provided reaction card.
   • Add the bacterial colony to the reagent and mix thoroughly using the provided stick.
4. Observation:
   • Observe for visible agglutination within 20 seconds.
5. Interpretation:
   • Positive Test: Agglutination (clumping) of the blue latex particles indicates the presence of S. aureus.
   • Negative Test: No agglutination; indicates a non-S. aureus staphylococcal species.
6. Control Testing:
   • Use the Negative Control Latex Reagent to ensure the specificity of the test.

Clinical Significance

• Rapid Diagnosis:
  • Enables quick identification of S. aureus, facilitating timely treatment of infections.
• Application Areas:
  • Commonly used in diagnosing infections like:
    • Skin and soft tissue infections.
    • Bloodstream infections.
    • Endocarditis.
    • Bone and joint infections.
• Infection Control:
  • Identifying S. aureus quickly aids in implementing infection control measures in healthcare settings.

Advantages

• Speed:
  • Delivers results in less than a minute, reducing turnaround time for diagnosis.
• Ease of Use:
  • No need for complex instruments or extensive training.
• High Accuracy:
  • Specificity for S. aureus minimizes false positives from coagulase-negative staphylococci.
• Cost-Effective:
  • Compact kit with all required reagents for up to 100 tests.
• Versatility:
  • Suitable for various staphylococcal isolates from different media.

Comparison with Other Kits

Regulatory Compliance

• CE-marked for in vitro diagnostic use.
• Compliant with international quality standards for diagnostic reagents.

Storage and Stability

• Store at 2–8°C to maintain reagent stability.
• Avoid freezing or exposure to high temperatures.

Conclusion

The Prolex™ Blue Staph Latex Kit (100T) is a highly reliable, fast, and easy-to-use diagnostic tool for the identification of Staphylococcus aureus. Its specificity, sensitivity, and straightforward testing protocol make it a valuable asset in clinical microbiology laboratories, ensuring timely and accurate diagnosis of staphylococcal infections.
