Sample Storage Requires Monitoring To Assure High Quality

By Tom Doerr


The latest information about sample storage and the quality control for the biological specimens stored is circulated in a newsletter published four times a year. According to scientists it is not possible to be too careful with these valuable materials. The correct results of testing can mean the difference between life and death for a patient in crisis.

That is why many laboratories have independent controls in place to monitor the samples and how they are stored. The independent control methods are used in addition to kit controls. If a lab uses kit controls alone, that may not be sufficient. Standards are increased by using both methods at the same time.

These samples are used for blood tests, donor screening, clinical trials and drug research, to name a few purposes. Samples are kept in repositories of different sizes and types of boxes, containers and closures. The materials are catalogued for store housing that uses a minimal amount of space. A depository set includes the partitioned box, vials to hold the materials, closures, labels, a chart and a card held in an exterior card holder.

Each storage component can be discovered separately or as a complete kit to hold like samples. The vials hold liquids and other specimens. The boxes are protected on the outside with abrasion resistant covering. Designed to be kept in incubators, refrigerators, freezers or at room temperature in a suitable facility, these individualized containers are available in many sizes.

Sometimes one of the research facilities runs out of room to store all its materials. They have a solution for that problem. Industry appropriate places are in the business of renting out storage for these sensitive samples. Technology is making advances in this area and the standards required to package and transport sensitive materials are at a high level.

The laboratories are able to have more space available by keeping them elsewhere. Exceptional safety precautions ensure the materials will be in perfect condition when returned to the labs as needed. Standards for sample storage are very important since they are being used for important research. The facility must maintain storage temperatures whether it is at a lab or a separate location.
