Plasma vacuum blood container

Understanding Plasma Vacuum Blood Containers

Plasma vacuum blood containers are essential tools in the medical field, designed for the collection and preservation of blood samples for diagnostic purposes. These containers are engineered to maintain the integrity of blood specimens, ensuring that the cellular components and plasma remain separated and uncoagulated until analysis.

Types and Applications

There are various types of blood collection tubes, each tailored for specific tests and analyses. For instance, tubes with lavender tops are typically used for Complete Blood Count (CBC) tests, containing an EDTA additive to prevent coagulation. Tubes with green tops, on the other hand, are used for Comprehensive Metabolic Panel (CMP) tests, utilizing sodium heparin as an anticoagulant. The color coding system is a standardized approach to identify the type of additive and the corresponding test for which the tube is intended.

Features and Specifications

Each plasma vacuum blood container comes with unique specifications that cater to different diagnostic requirements. The containers are designed with a vacuum seal to ensure the precise volume of blood is drawn directly from the vein into the tube. This feature minimizes the risk of contamination and ensures the sample's viability for testing. The materials used in these containers are also carefully selected to be compatible with the blood and the additives, preventing any adverse reactions that could compromise the sample.

Materials and Advantages

The materials used in blood collection tube production are critical for sample integrity. High-quality plastics or glass are commonly used to prevent any interaction with the blood sample. The advantages of using these materials include chemical inertness, durability, and transparency, which are essential for accurate analysis. Additionally, the use of anticoagulants and other additives in these containers helps preserve the blood samples for extended periods, allowing for more flexibility in testing schedules.

Selection and Usage

Selecting the right blood test tubes is crucial for accurate diagnostic results. It is important to choose the appropriate tube type based on the test to be conducted. For example, Serum Separating Tubes (SST) with gold or yellow tops are used when serum separation from blood cells is required. Understanding the purpose and function of each tube type is essential for healthcare professionals to ensure that the blood sample is processed correctly.

Procurement through Alibaba.com

For businesses in need of reliable blood collection supplies, Alibaba.com offers a comprehensive platform to connect with international wholesale suppliers. It is possible to find a wide array of plasma vacuum blood containers with the necessary specifications to meet diverse diagnostic needs. When procuring these containers, it is important to consider the type of analysis to be performed and the corresponding tube that is required for accurate results.
