ESR Blood Collection Tube

Vacuum ESR blood collection tubes are disposable medical devices used in clinical tests for the safe and precise collection of venous blood samples. The core principle is to automatically draw a fixed amount of blood by utilizing the preset vacuum negative pressure inside the tube and react it with the pre-added reagents in the tube to ensure the quality of the sample and the accuracy of the test.

I. Product Function and Key Attributes

This blood collection container contains sodium citrate anticoagulant at concentrations of 3.2% (0.109 mol/L) or 3.8%. Its mode of action involves chelating calcium ions to halt coagulation while preserving a precise 4:1 blood-to-anticoagulant proportion, thereby maintaining consistent red cell morphology and plasma viscosity characteristics. Key attributes include:

Standard-Compliant Construction:

Meets dimensional requirements for erythrocyte sedimentation tubes established by the International Council for Standardization in Haematology (ICSH).

Incorporates pre-loaded anticoagulant to achieve accurate 4:1 dilution, eliminating dilution errors.

Clear Tube Architecture:

Manufactured from precision-molded glass or medical-grade polymers, featuring distinct calibration markers that allow unobstructed visualization of the sedimentation boundary.

Consistent and Reproducible Outcomes:

Faithfully implements the classic Westergren technique, ensuring alignment with historical data and internationally accepted reference intervals.

II. Main Application Settings

This product is specifically designed for erythrocyte sedimentation rate (ESR) determination and serves as a valuable diagnostic aid in clinical scenarios including:

Identification and tracking of inflammatory conditions (such as infections, tubercular diseases)

Assessment of disease progression in autoimmune and rheumatic disorders (including rheumatoid arthritis, systemic lupus erythematosus)

Complementary diagnostic tool for chronic conditions involving hematologic abnormalities and malignant diseases

Surveillance of systemic inflammatory responses in specialized fields including geriatric medicine and perinatal care
