Products Description

Products Introduction

Anticoagulant: The tube is preloaded with a specific concentration of sodium citrate anticoagulant, commonly concentration of 3.2% or 3.8% (0.109 mol/L or 0.129 mol/L), which serves to prevent blood from coagulating inside the tube.

Mixing ratio: It requires that during blood collection, the volume ratio of blood to anticoagulant must be strictly 4:1. This precise ratio is the prerequisite for ensuring the accuracy of the test results.

Design Foundation: The black cap is its internationally recognized signature color, making it easy for medical staff to quickly identify it. The entire tube body is made of medical-grade glass or PET plastic and undergoes strict sterilization treatment.

Application Areas

Its application areas are highly specialized and important, mainly focused on a core clinical testing project:

Core use: for measuring erythrocyte sedimentation rate (ESR). This test is a commonly used indicator to assess whether inflammation, infection, or tissue damage is present in the body.

Clinical value: It has important reference value for screening, auxiliary diagnosis, and monitoring of various diseases, such as acute and chronic infections, autoimmune diseases (such as rheumatoid arthritis), malignant tumors, and tissue damage.

Core Advanatges

Standardization and accuracy: Vacuum blood collection technology ensures precise blood volume, thereby guaranteeing a precise 4:1 ratio of blood to anticoagulant and avoiding manual errors, which is the foundation for reliable results.

Convenient and safe operation: plug-and-use, works with the lancet for quick operation. The enclosed vacuum system reduces contact between blood samples and the outside world, protecting samples from contamination and lowering the risk of occupational exposure for healthcare workers.

Reliability of results: Its design complies with the internationally recognized Westergren method testing requirements. Many products also use atomization spraying technology to evenly adhere anticoagulants to the tube walls, ensuring rapid and thorough mixing with blood and further improving result stability.

Slender ESR Tube

The slender ESR blood collection tube is a vacuum tube specifically designed for detecting erythrocyte sedimentation rate (ESR).

Its core feature is that its tube length design matches the internationally recognized "gold standard" testing method-the Westergren method-aiming to obtain more standard and reliable inspection results.

Difference between ESR Tubes and Slender ESR Tube

products
Contrast Dimensions	ESR tube	Slender ESR tube
Tube Body	Short and thick	Long and thin
core Difference	The testing principle differs from the standard method	Closer to or fully compliant with the standards of the Westergren Law
Test method	Usually used in combination with automation or specific instruments, the results may need to be corrected according to tubing length	The design is intended to directly apply the Westgren method, so reading results does not require tube length correction
Accuracy	For high-value ESR (e.g., > 55mm/hr), sensitivity is limited by tube length, and results are usually considered semi-quantitative, with some deviation	Because the tube length is close to the standard, it can measure high values more accurately, and the results of methods recommended by the International Committee for Hematology Standardization (ICSH) are highly correlated
Clinical Application	Suitable for routine screening, easy to operate, and common in highly automated laboratories	It is especially suitable for scenarios requiring higher accuracy of erythrocyte sedimentation rate results or when comparison with standard methods is needed, making it the preferred choice for many laboratories seeking result traceability
