Coagulation tests play a critical role in diagnosing and monitoring various clotting disorders, ensuring appropriate medical interventions. Clot Activator Tubes (CATs) are essential specimens that facilitate the initiation of the coagulation cascade, leading to the formation of a stable clot. This article provides a comprehensive overview of CATs, their components, uses, and best practices in specimen collection and handling.
CATs are specialized blood collection tubes containing clot activators, which trigger the coagulation cascade. The most common type of clot activator used is silica, a glass-like material that activates Factor XII (Hageman factor), initiating the intrinsic coagulation pathway.
Other clot activators include:
The type of clot activator used depends on the specific coagulation tests being performed.
CATs are primarily used for collecting blood samples for coagulation studies, including:
1. What is the recommended sample volume for a CAT?
The ideal sample volume for a CAT varies depending on the specific laboratory test being performed. Consult the laboratory's guidelines or equipment manufacturer's recommendations.
2. Can I mix multiple samples in a CAT?
No, it is not recommended to mix multiple samples in the same CAT. Each patient sample should be collected and tested separately.
3. What if the sample clots before I can invert it?
If the sample clots before inverting, gently tap the tube to dislodge the clot and proceed with inversion to ensure proper mixing.
4. Can I use a CAT for other blood tests besides coagulation studies?
CATs are specifically designed for coagulation testing. Using them for other types of blood tests may interfere with those assays.
5. What is the difference between a CAT and a plain blood collection tube?
CATs contain clot activators that trigger coagulation, while plain blood collection tubes do not.
6. How can I ensure the accuracy of coagulation test results?
Follow the manufacturer's instructions for proper collection, handling, and storage of CAT samples.
Clot Activator Tubes are essential tools for accurate and reliable coagulation testing. By understanding their components, uses, and best practices for specimen collection and handling, healthcare professionals can contribute to high-quality patient care.
