Article

Apr 6

Medical supplies are an essential component of healthcare, ensuring that healthcare professionals have the tools they need to diagnose and treat patients effectively. Among these supplies, blood collection tubes play a crucial role in collecting blood samples for various tests and analyses. In the United States, there are several different types of blood collection tubes available, each designed for specific purposes. In this article, we will explore the different types of blood collection tubes used in the US, their uses, and the importance of proper handling and storage.

The Importance of Blood Collection Tubes

Blood collection tubes are used to collect blood samples from patients for various diagnostic tests, such as blood cell counts, cholesterol levels, and glucose levels. These tubes are essential for providing accurate and reliable test results, which are crucial for diagnosing diseases, monitoring treatment efficacy, and assessing overall health status.

There are several different types of blood collection tubes available, each containing specific additives designed to preserve the integrity of the blood sample and ensure accurate test results. The most commonly used blood collection tubes in the US include:

Types of Blood Collection Tubes

1. Serum Tubes

Serum tubes are used to collect blood samples for tests that require serum, such as cholesterol, liver function, and hormone levels. These tubes typically contain a clotting activator, such as silica particles or glass beads, which promote blood clotting and facilitate the separation of serum from the blood cells. The most common serum tubes used in the US are the red-topped tubes, which are color-coded for easy identification.

2. Plasma Tubes

Plasma tubes are used to collect blood samples for tests that require plasma, such as coagulation studies and drug level monitoring. These tubes contain an anticoagulant, such as EDTA, heparin, or citrate, which prevents blood clotting and preserves the integrity of the plasma. The most common plasma tubes used in the US are the lavender-topped tubes, which are also color-coded for easy identification.

3. Hematology Tubes

Hematology tubes are used to collect blood samples for complete blood count (CBC) tests, which assess the number and types of blood cells present in the sample. These tubes typically contain an anticoagulant, such as EDTA or citrate, which prevents blood clotting and preserves the integrity of the blood cells. The most common hematology tubes used in the US are the lavender-topped tubes, which are also color-coded for easy identification.

Proper Handling and Storage

Proper handling and storage of blood collection tubes are essential for ensuring the integrity of the blood sample and the accuracy of the test results. Here are some important guidelines to follow when using blood collection tubes:

Store blood collection tubes in a cool, dry place away from direct sunlight and extreme temperatures.
Avoid shaking or agitating the tubes, as this can cause hemolysis and affect the test results.
Label the tubes correctly with the patient's name, date of birth, and other relevant information to prevent sample mix-ups.
Follow the manufacturer's instructions for proper tube handling and storage, including the recommended storage temperature and expiration date.

Conclusion

Blood collection tubes are essential medical supplies used in healthcare settings to collect blood samples for diagnostic tests and analyses. In the US, there are several different types of blood collection tubes available, each designed for specific purposes and containing specific additives to preserve the integrity of the blood sample. Proper handling and storage of blood collection tubes are essential for ensuring the accuracy and reliability of test results. By following the guidelines outlined in this article, healthcare professionals can ensure that blood collection tubes are used effectively and provide accurate diagnostic information for patient care.
