Disposable Vacuum Slender ESR Blood Collection Tube

I. Product Functionality and Core Characteristics

This blood collection tube contains a sodium citrate anticoagulant at a concentration of either 3.2% (0.109 mol/L) or 3.8%. Its mechanism of action involves binding calcium ions in the blood to prevent coagulation while maintaining a strict 4:1 blood-to-anticoagulant ratio, thereby preserving erythrocyte morphology and plasma properties. Key features are as follows:

Specification-Compliant Design:

Conforms to the dimensional standards for erythrocyte sedimentation rate (ESR) tubes established by the International Council for Standardization in Haematology (ICSH).

Contains a pre-measured anticoagulant to ensure an accurate 4:1 dilution ratio, minimizing measurement errors.

Transparent Tube Design:

Manufactured from precision-molded glass or medical-grade polymer materials, featuring clear calibration markings for easy observation of the sedimentation interface.

II. Primary Application Scenarios

This product is specifically designed for erythrocyte sedimentation rate (ESR) testing and serves as an important auxiliary diagnostic tool in the following clinical contexts:

Detection and monitoring of inflammatory conditions (e.g., infectious diseases, mycobacterial infections)

Evaluation of disease progression in autoimmune and rheumatologic disorders (e.g., rheumatoid arthritis, systemic lupus erythematosus)

Supporting diagnosis in chronic conditions such as hematologic disorders and tumors

Observation of systemic inflammatory markers in clinical fields including geriatrics and perinatal medicine

III. Product Specifications and Operating Procedures

Anticoagulant Specification: Sodium citrate solution at 3.2% (recommended) or 3.8% concentration

Visual Identification Feature: Black cap (internationally recognized color coding)

Key Operating Steps:

Blood Collection and Mixing: Collect venous blood to the specified volume (1.6 mL for 3.2% concentration / 1.28 mL for 3.8% concentration), then gently invert the tube 5–8 times immediately to ensure thorough mixing.

Instrument Preparation and Placement: Transfer the mixed blood sample into a standardized Westergren sedimentation tube until the "0" mark is reached, then place it vertically in a dedicated sedimentation rack.

Reading: After standing undisturbed for 60 minutes under controlled room temperature (18–25°C), record the distance of erythrocyte sedimentation, with results expressed in millimeters per hour (mm/h).
