Professional FAQ on K EDTA Tubes

1. What is the primary function of a k edta tube?

The primary function of a k edta tube is to collect whole blood samples and prevent them from clotting. It achieves this by using K2EDTA (Dipotassium Ethylenediaminetetraacetic acid) as an anticoagulant, which chelates (binds to) calcium ions, essential for the coagulation cascade, thereby preserving the cellular components and plasma for various diagnostic tests, particularly in hematology and molecular diagnostics.

2. What is the difference between K2EDTA and K3EDTA in blood collection tubes?

Both K2EDTA and K3EDTA function as anticoagulants. However, K2EDTA is generally preferred by international standardization bodies like ICSH and CLSI because it has less impact on red blood cell morphology (minimal cell shrinkage) and volume, and causes less dilution of the blood sample compared to K3EDTA, which is supplied as a liquid and can lead to up to 2% dilution. This makes K2EDTA more suitable for accurate hematological parameters.

3. What is the standard fill volume tolerance for an EDTAK2 tube?

The standard fill volume tolerance for an EDTAK2 tube is typically +/- 10% of the nominal fill volume, as per CLSI guidelines. This ensures the correct blood-to-anticoagulant ratio, which is crucial for preventing clotting (if underfilled) or dilution errors (if overfilled). Precision vacuum manufacturing guarantees this tolerance.

4. How does the vacuum system in a K EDTA tube work?

The vacuum in a K EDTA tube is pre-set during manufacturing by precisely evacuating air from the tube and sealing it with a rubber stopper. When a needle pierces the stopper after venipuncture, the vacuum draws blood into the tube until a specific volume is reached. This negative pressure system ensures consistent and accurate blood draw volumes, eliminating the need for manual blood measurement and preventing over/underfilling.

5. What materials are typically used in the manufacturing of k edta vacutainer tubes?

K EDTA vacutainer tubes are typically manufactured from medical-grade Polyethylene Terephthalate (PET) plastic for the tube body, which offers excellent transparency, strength, and gas barrier properties. The stopper is usually made from a specialized rubber compound, while the cap is made from a compatible plastic (e.g., polyethylene). The inner surface is coated with a precise amount of K2EDTA salt.

6. What quality standards should I look for in k2 edta blood collection tubes?

When selecting k2 edta blood collection tubes, look for manufacturers adhering to international quality standards such as ISO 13485 (Medical Devices Quality Management System), CE marking (for European markets), and FDA registration (for the U.S. market). Adherence to CLSI (Clinical and Laboratory Standards Institute) guidelines, particularly H01-A6 for blood collection, also indicates high quality and reliability.

7. What is the shelf life of an EDTAK2 tube and how should it be stored?

The typical shelf life of an EDTAK2 tube is between 18 to 24 months from the manufacturing date. To maintain their integrity and performance, these tubes should be stored at room temperature (typically 4-25°C or 39-77°F), away from direct sunlight and extreme temperatures or humidity. Proper storage ensures the vacuum remains intact and the K2EDTA additive retains its efficacy.
