. Function & Key Features
This blood collection tube uses sodium citrate at 3.2% (0.109 mol/L) or 3.8% as the anticoagulant. It works by binding calcium ions to block coagulation while maintaining an exact 4:1 blood-to-anticoagulant ratio, preserving red cell integrity and plasma properties. Main features include:
Standard-Compliant Build:
Meets ICSH dimensional specs for ESR tubes.
Pre-loaded anticoagulant ensures accurate 4:1 dilution, minimizing volume errors.
Clear Tube Design:
Made from precision-molded glass or medical-grade polymer, with clear markings for easy reading of the sedimentation line.
II. Primary Applications
Designed specifically for ESR testing, this tube supports diagnosis in areas such as:
Detecting and tracking inflammation (e.g., infections, TB)
Monitoring autoimmune/rheumatic diseases (e.g., rheumatoid arthritis, lupus)
Supporting diagnosis in chronic conditions like blood disorders or cancers
Observing inflammation in geriatric or perinatal care
