Understanding Blue Top Sodium Citrate Tubes

Blood collection is a critical process in medical diagnostics, and the blue top sodium citrate tube plays a pivotal role in this procedure. These tubes are specifically designed for blood coagulation tests and are an essential component in the array of blood collection devices. The blue cap signifies the presence of sodium citrate, which acts as an anticoagulant, binding calcium in the blood and preventing clotting.

Types and Applications

The application of coagulation test tubes extends to various diagnostic tests, including prothrombin time (PT) and activated partial thromboplastin time (aPTT). Each tube is crafted to maintain the integrity of the blood sample, ensuring that the cellular components and plasma are preserved for accurate analysis. The blue top tubes are also utilized in platelet function tests, making them a versatile tool in the medical testing field.

Features and Specifications

A blue top tube is distinguished by its unique features. The concentration of sodium citrate within these tubes is standardized to ensure consistency in blood-to-anticoagulant ratios. This precision is crucial for the reliability of coagulation assays. The tubes are also available in various draw volumes to accommodate different testing requirements and patient needs.

Materials and Advantages

The materials used in anticoagulant blood tubes are selected for their compatibility with blood samples and their non-reactivity. The interior surface of the tube is often treated to be as inert as possible, to prevent any interference with the test results. The advantage of using sodium citrate as an anticoagulant lies in its ability to be easily neutralized during processing, which is essential for certain assays that require clotting to occur as part of the test.

Selection and Usage

When selecting a blood collection tube, it is important to consider the specific requirements of the test to be performed. The blue top sodium citrate tubes are designed for single-use, ensuring sterility and preventing cross-contamination. Proper usage involves filling the tube to the designated volume to maintain the correct ratio of blood to anticoagulant, which is critical for accurate test results.

Procurement through Alibaba.com

For businesses in need of reliable blood collection supplies, sourcing blue top sodium citrate tubes through Alibaba.com offers a convenient and efficient solution. The platform connects buyers with a diverse range of international suppliers, providing access to products that meet various specifications and testing needs without endorsing any specific brands or making qualitative claims.
