Orsin Medical Technology ESR Blood Collection Tubes

Orsin Medical Technology's ESR Blood Collection Tubes are designed for precise and efficient erythrocyte sedimentation rate (ESR) testing in clinical settings. These tubes ensure reliable results through strict adherence to international standards and advanced manufacturing processes.

Product Highlights: Technological Innovation Ensures Accuracy

ESR tubes incorporate advanced engineering to deliver superior clinical performance:

Scenario Type	Application Description	Target Users	Key Benefits
Clinical Diagnostics	Routine ESR testing for inflammation monitoring in hospitals and clinics.	Pathologists, Lab Technicians	Standardized anticoagulant ensures accurate results for diagnostic consistency.
Autoimmune Disease Management	Tracking disease activity in conditions like rheumatoid arthritis or lupus.	Rheumatologists, Immunologists	Reliable ESR data supports treatment adjustment and progression monitoring.
Infection Monitoring	Assessing inflammatory responses in bacterial infections, sepsis, or postoperative care.	Infectious Disease Specialists, Surgeons	Rapid and precise ESR measurement aids in infection control and recovery assessment.
Research Studies	Academic or clinical research involving inflammatory biomarkers.	Researchers, Biotechnologists	High sample clarity and compliance with international standards support data validity.
Primary Care Screening	Initial inflammation screening in community healthcare settings.	General Practitioners, Nurses	Easy identification (black cap) reduces sampling errors and improves workflow efficiency.
Pediatric & Geriatric Care	ESR testing for age-specific inflammatory conditions (e.g., childhood infections or aging-related diseases).	Pediatricians, Geriatricians	Gentle vacuum design and safety-certified materials minimize patient discomfort.

Usage Precautions: Standardized Operations Ensure Reliability

3.1 Pre-collection Preparation

Tube Selection: Verify black-capped ESR-specific tubes contain 3.8% sodium citrate. Inspect for particulates, sedimentation, or cap looseness.
Storage Conditions: Store at 4-25°C. Avoid freezing (causes tube fracture) or high temperatures (degrades anticoagulant).
Patient Preparation: Collect blood from calm, preferably fasting patients. Note non-fasting status on requisition forms.

3.2 Blood Collection Protocol

Order of Draw: Follow international sequence: blood culture → coagulation tubes → other anticoagulant tubes → ESR tubes (black cap). Prevents anticoagulant cross-contamination.
Exact Fill Volume: Draw precisely to fill line (typically 2mL). Underfilling causes false-low ESR; overfilling promotes microclot formation.
Mixing Technique: Gently invert 5-10 times immediately after collection. Avoid vigorous shaking to prevent partial anticoagulation or hemolysis.

3.3 Post-collection Handling

Testing Timeline: Analyze within 2 hours. Delayed testing alters erythrocyte morphology. Store at 18-25°C if necessary (NEVER refrigerate).
Tube Orientation: Transport upright to avoid disturbing sedimentation.
Sample Rejection Criteria: Reject clotted, severely hemolyzed, improperly filled (>±10%), unlabeled, or damaged specimens.

*Note: 30% of ESR errors originate from pre-analytical issues, primarily inaccurate fill volumes and improper mixing.*
