How should I store a tick for laboratory analysis?

Collection and Preservation Methods

When collecting and preserving ticks for laboratory analysis, it is essential to follow proper techniques to ensure accurate results. The tick should be removed from the skin as soon as possible using fine-tipped tweezers, taking care to grasp the tick’s mouthparts as close to the skin as possible. This will minimize the amount of tick saliva and other contaminants that may be introduced during removal.

Storage and Transportation

Once removed, the tick should be placed in a sealed container, such as a 15-mL conical tube or a plastic vial with a screw-top lid. The container should be filled with a preservative, such as 70-80% ethanol or isopropanol, to a depth of at least 10-15 mm. The tick should be completely submerged in the preservative to prevent degradation and contamination. If using a screw-top lid, ensure it is tightened securely to prevent leakage. Label the container with the date, time, and location where the tick was collected, as well as any relevant patient information.

Transportation and Handling

When transporting the tick to the laboratory, it is essential to keep it in a sealed container and maintain a consistent temperature between 2-8°C (36-46°F). Avoid exposure to direct sunlight, extreme temperatures, or vibrations, which can cause the tick to degrade or become damaged. If transporting the tick over an extended period, consider using a cooler with ice packs to maintain a consistent temperature. Handle the tick container with gloves to prevent contamination and minimize the risk of tick-borne pathogens.
