K2/K3 EDTA Anticoagulant Vacuum Blood Collection Tube

In clinical testing and medical diagnosis, the stability of blood samples plays a critical role in ensuring accurate test results. The K2/K3 EDTA anticoagulant vacuum blood collection tube is a widely used disposable medical consumable designed to prevent blood coagulation while preserving the morphology and composition of blood cells. It is commonly used in hospitals, clinical laboratories, health check centers, and medical research facilities.

What Is a K2/K3 EDTA Anticoagulant Vacuum Blood Collection Tube?

A K2/K3 EDTA anticoagulant vacuum blood collection tube is a vacuum tube pre-loaded with EDTA (ethylenediaminetetraacetic acid) salt as an anticoagulant. The most common forms are K2 EDTA and K3 EDTA. EDTA works by binding to calcium ions in the blood, effectively preventing clot formation and keeping the blood sample in a liquid state for laboratory analysis.

Difference Between K2 EDTA and K3 EDTA

K2 EDTA is usually applied as a dry spray coating on the inner wall of the tube and has minimal impact on blood cell volume. K3 EDTA is typically added in liquid form and requires precise control of blood volume during collection. Both types are widely used in routine hematology testing.

Working Principle

Once blood enters the K2/K3 EDTA anticoagulant vacuum blood collection tube, EDTA immediately binds with calcium ions and stops the coagulation cascade. This keeps the blood sample stable and suitable for accurate hematological analysis.
