D-Shield microbial evidence extraction swabs are specialized tools used for collecting microbial samples from surfaces, fluids, or biological materials in various environments. These swabs are designed to preserve microbial integrity, making them essential for forensic investigations, clinical diagnostics, and environmental testing.
Operational Guide:
-
Preparation: Ensure the swabs are sterile and individually packaged. Wear gloves to prevent contamination and use appropriate protective gear when handling biological materials.
-
Sample Collection: Gently swab the surface or specimen area where microbial evidence is suspected. Ensure even and thorough coverage of the area to collect a representative sample.
-
Storage: Immediately place the swab in a sterile transport container, ensuring it is sealed tightly to maintain sample integrity.
-
Labeling: Properly label the sample with relevant details such as time, location, and the type of sample to ensure traceability and prevent misidentification.
-
Transport: Transport the samples to the laboratory promptly, adhering to the chain of custody protocol to ensure the sample is not tampered with or degraded during transit.
Extraction Techniques:
-
Microbial Preservation: The swabs are designed to stabilize microbial samples immediately after collection, preventing loss of viability during transport.
-
DNA/RNA Isolation: After collection, the swabs can be used to extract DNA or RNA for analysis using techniques like PCR, sequencing, or culture-based methods.
Key Features:
-
Sterile and Individually Packaged: Ensures no contamination during storage and transport.
-
Efficient Collection: Designed to collect a wide range of microbial evidence, from bacteria to fungi.
-
Durable: Maintains microbial integrity during extraction and transport.
-
Versatile: Suitable for various forensic, clinical, and environmental applications.
Scope:
D-Shield swabs are widely used in forensic science, clinical microbiology, environmental contamination studies, and epidemiological investigations, ensuring reliable microbial evidence collection.
