Hematocrit Tubes Heparinized: Essential Tools for Precision Diagnostics

Hematocrit tubes heparinized are critical components in modern clinical laboratories, designed to prevent coagulation in capillary blood samples. These tubes, typically manufactured from borosilicate glass or polymer resins, enable accurate measurement of packed cell volume (PCV). With an average internal diameter of 1.1-1.5 mm and lengths ranging from 75-100 mm, they demonstrate 98.7% clot prevention efficiency compared to non-heparinized alternatives.

Technical Superiority in Blood Analysis

Advanced heparinized tubes feature:

• Uniform heparin coating (12-15 IU per tube)
• Centrifugal force tolerance up to 12,000 RCF
• Color-coded identification systems

Independent testing shows heparinized models reduce result variability by 43% versus plain capillary tubes in hematocrit determination.

FAQS on hematocrit tubes heparinized

Q: What are heparinized hematocrit tubes used for?

A: Heparinized hematocrit tubes are designed to prevent blood clotting by coating the tube with heparin, an anticoagulant. They are commonly used for collecting and analyzing small blood samples in hematocrit tests.

Q: What is the difference between heparinized and non-heparinized capillary tubes?

A: Heparinized capillary tubes contain an anticoagulant to prevent clotting, making them ideal for plasma separation. Non-heparinized tubes lack this coating and are used for serum separation after blood clotting occurs.

Q: Can micro hematocrit tubes be used without heparin?

A: Yes, micro hematocrit tubes are available in both heparinized and non-heparinized variants. The choice depends on whether anticoagulation is required for the specific test or analysis.

Q: How do I choose between heparinized and non-heparinized tubes for blood sampling?

A: Select heparinized tubes if immediate anticoagulation is needed for tests like hematocrit or plasma analysis. Use non-heparinized tubes when serum is required, allowing blood to clot naturally before centrifugation.

Q: Are heparinized capillary tubes reusable?

A: No, heparinized capillary tubes are designed for single-use to avoid cross-contamination and ensure accurate results. Reusing them may compromise sample integrity and test reliability.
