Blood Specimen Storage and Transport

Proper storage and transport of blood specimens are crucial steps in the process of ensuring accurate and reliable laboratory test results. In this article, we will discuss the importance of proper blood specimen storage and transport, as well as best practices to follow in order to maintain the integrity of these samples.

Importance of Proper Blood Specimen Storage and Transport

When blood specimens are collected for laboratory testing, they contain valuable information about a patient's health. It is essential that these samples are handled and stored properly in order to prevent contamination or degradation of the sample, which could lead to inaccurate test results.

Proper storage and transport of blood specimens are especially important when dealing with sensitive tests, such as genetic testing or molecular diagnostics, where even slight changes in temperature or exposure to light can affect the results.

Factors Affecting Blood Specimen Stability

There are several factors that can affect the stability of blood specimens, including:

1. Temperature: Blood specimens should be stored at the appropriate temperature to prevent degradation of the sample.
2. Exposure to light: Exposure to light can cause certain substances in the blood to break down, leading to inaccurate test results.
3. Time: Blood specimens should be transported to the laboratory in a timely manner to prevent changes in the sample over time.

Best Practices for Blood Specimen Storage and Transport

Follow these best practices to ensure proper storage and transport of blood specimens:

Storage Conditions

1. Store blood specimens at the recommended temperature specified by the test manufacturer.
2. Avoid repeated freeze-thaw cycles, as this can lead to degradation of the sample.
3. Label each specimen with the patient's name, date and time of collection, and any other relevant information.

Transportation

1. Use appropriate packaging materials to prevent breakage or leakage of blood specimens during transport.
2. Keep specimens at the correct temperature during transport, using cold packs or insulated containers if necessary.
3. Ensure that specimens are delivered to the laboratory in a timely manner to prevent changes in the sample over time.

Documentation

It is important to maintain accurate documentation of the storage and transport of blood specimens. This documentation should include:

1. Date and time of specimen collection
2. Date and time of specimen storage and transport
3. Temperature at which the specimen was stored and transported
4. Name of the person responsible for handling the specimen
