Handling and Transporting Coagulation Specimens for Accurate Test Results

Summary

• Improper mixing of coagulation specimens can lead to inaccurate results.
• Transporting coagulation specimens at the wrong temperature can also cause errors.
• It is important to follow proper protocols for handling and transporting coagulation specimens to ensure accurate results.

Introduction

Transporting coagulation specimens is a critical step in the laboratory testing process. These specimens are often fragile and prone to errors if not handled and transported correctly. In this article, we will discuss a common error in the transportation of coagulation specimens and how to avoid it.

Improper Mixing

One common error in the transportation of coagulation specimens is improper mixing. Coagulation specimens, such as blood samples for Prothrombin Time (PT) and Activated Partial Thromboplastin Time (aPTT) tests, need to be mixed thoroughly after collection to ensure accurate results. If the specimen is not mixed properly, the Anticoagulant may not be evenly distributed, leading to inaccurate Test Results.

How to Avoid This Error

To avoid the error of improper mixing, it is important to follow these steps:

1. Gently invert the specimen tube several times immediately after collection to mix the blood with the anticoagulant.
2. Avoid vigorous shaking, as this can cause hemolysis and affect Test Results.
3. Label the specimen tube with the patient's information and the time of collection to ensure proper identification.

Transporting at the Wrong Temperature

Another common error in the transportation of coagulation specimens is transporting them at the wrong temperature. Coagulation tests are sensitive to temperature fluctuations, and transporting the specimens at the wrong temperature can lead to inaccurate results. For example, if the specimen is exposed to extreme heat or cold during transport, it can affect the activity of clotting factors and impact Test Results.

How to Avoid This Error

To ensure that coagulation specimens are transported at the correct temperature, follow these guidelines:

1. Use insulated packaging or temperature-controlled containers to transport specimens that require specific temperature conditions.
2. Check the temperature requirements for each coagulation test and ensure that the specimens are maintained within the appropriate temperature range during transport.
3. If ambient temperature requirements are specified, do not expose the specimens to extreme temperatures during transit.

Conclusion

Transporting coagulation specimens accurately is essential for obtaining reliable Test Results. By avoiding common errors such as improper mixing and transporting specimens at the wrong temperature, laboratory professionals can ensure that coagulation tests are performed accurately and provide valuable information for patient care.
