• Urine and saliva samples: It’s essential to use leak-proof, properly labeled containers to avoid contamination or tampering during transportation.
• Tissue and biopsy samples: Special handling requirements may be necessary for tissue and biopsy samples to avoid deterioration and degradation of the samples during transportation.

How to Choose the Right Transport Containers for Lab Specimens

Choosing the right container for transporting lab samples is critical to protect the integrity and preserve the quality of specimens during transportation. The containers should be compatible with the specimen type and safe for transportation by the selected mode of transport.

Depending on the type of sample and mode of transport, the container material can vary from leak-proof plastic bags, screw-capped tubes, or ice-packed Styrofoam containers. The container’s design should also facilitate easy identification and labeling, and it should provide adequate temperature and moisture protection for the specimen during transport, depending on the sample’s sensitivity.

Preparing Lab Specimens for Transport: Tips and Tricks

Proper preparation of laboratory samples for transport is essential to avoid any mishaps or accidents during transportation. Before transporting any specimen, there are several things to consider and follow to ensure their safety.

Some of the best practices to prepare samples for transport include labeling samples with the patient’s name, identification number, date, and time of collection and ensuring compliance with laboratory regulatory requirements. Precooled or preservative-treated containers may be necessary to maintain sample stability during transport and ensure safe and secure packaging.

Ensuring Temperature Control During Specimen Transport

Temperature control is critical during the transport of laboratory specimens to avoid degradation of delicate samples or biological organisms’ growth. Temperature-sensitive specimens, such as blood or urine samples, need to be maintained at specific temperatures to preserve their integrity during transport.

To ensure proper temperature control, use thermal-insulating material such as dry ice, ice packs, gel packs, or insulated coolers that can maintain the required temperature range during transportation. It’s also crucial to monitor the temperature of specimens frequently to ensure they remain within the required range, especially during transit periods of more than 24 hours.

How to Label and Track Lab Specimens During Transport

Proper labeling is essential for safe and efficient transportation of laboratory specimens. Each sample must be correctly labeled and accurately identified using the established protocols to guarantee correct testing and avoid confusion or sample misplacement.

Furthermore, laboratories should establish a system for tracking laboratory specimens to monitor the status and location of each sample from collection to delivery. This allows for easy verification of sample integrity and proper performance of tests, preventing discrepancies or delays in the results. This system should include methods of tracking samples through bar-codes, radio frequency ID (RFID), and other tracking technologies.
