6. Professional Terminologies FAQ
Q1: What is the primary material used in sodium heparin blood collection tubes, and why?
A: Most sodium heparin blood collection tubes use borosilicate glass or medical-grade PET. Both offer high transparency, robust chemical resistance, and endure high centrifugation speeds without deformation, ensuring sample integrity.
Q2: What are the typical specifications (size, additive) available?
A: Standard tube diameters range from 13mm to 16mm, lengths from 75mm to 120mm. Sodium heparin is coated at 12–30 IU/ml. Custom pediatric tubes and micro-volumes are available.
Q3: How does the installation standard (ISO/FDA) ensure consistency and safety?
A: ISO 6710 and FDA 510(k) outline dimensional, sterility, and closure integrity checks. Every batch is subjected to validation for leak-proofing, pyrogenicity, clarity, and additive efficiency before release.
Q4: Can sodium heparin tubes be used for all blood tests?
A: No, they are ideal for plasma biochemistry, electrolytes, and ammonia analysis, but not recommended for hematology (as heparin alter cell morphology), nor for coagulation studies (inhibits all clotting).
Q5: What quality assurance protocols are followed during production?
A: Production under ISO 13485:2016/ISO 6710, batch sterility validation, random destructive testing (drop/break test), and regular trace heavy metal analysis especially for royal blue top sodium heparin tubes.
Q6: How is Heparin Sodium sourced and tested?
A: High-purity Heparin Sodium is extracted from porcine mucosa; each lot undergoes potency, absence-of-pyrogen, and endotoxin tests as per USP and WHO standards before application.
Q7: What is the shelf life and storage requirement for sodium heparin blood collection tubes?
A: 24–36 months under standard room temperature (≤25℃), away from direct sunlight and excess humidity. Sterility and additive efficacy are batch tracked.
