Transportation of samples from the collection point to the laboratory, as well as storage and preservation techniques, are crucial for maintaining sample integrity and ensuring accurate and reliable test results.

Samples should be transported carefully from collection points to the laboratory. They should be properly sealed and clearly labeled to prevent cross-contamination. To preserve the sample integrity, optimal temperature conditions during transport are essential. This could involve using insulated containers, cool packs, or refrigerated vehicles to maintain the required temperature range.

Once the samples reach the laboratory, appropriate storage conditions must be implemented based on the sample type. For example, biological samples often require refrigeration or freezing, while others may need to be kept at room temperature. Light-sensitive samples need protection from sunlight, which can be achieved using opaque containers or wrapping the samples in light-blocking materials.

Preservation techniques vary widely depending on the nature of the sample. In chemical preservation, certain chemicals can be added to the samples to prevent microbial growth or chemical reactions that might alter the sample. If blood samples are collected, adding appropriate anticoagulants can prevent clotting and maintain the integrity of cellular components during storage.
