Green Blood Collection Tube

Features of Heparin Tube Heparin: Heparin tubes are coated with heparin, which is a naturally occurring substance that prevents blood coagulation. Heparin acts by inhibiting the activity of thrombin and other clotting factors, thus keeping the blood in a liquid state. Color-coded: Heparin tubes are typically color-coded to indicate their purpose. The green color coding helps healthcare professionals identify the correct tube for blood collection and ensures compatibility with specific laboratory tests. Inverted mixing: Heparin tubes usually require gentle inversion or mixing after blood collection to ensure proper mixing of the anticoagulant with the blood. This helps to prevent clotting and ensures that the sample remains in a suitable condition for laboratory analysis.
