These Vacutainer blood tubes are used when drawing blood. The tubes contain a vacuum that allows them to draw the blood from the vein itself. A vacutainer is connected to a venoject, which is the actual needle with holder for the tube. This type of vacutainer has a Hemogard closure
The Vacutainer blood tubes are available in various types with caps in various colours. This color cap has a meaning. It indicates the anticoagulant that is processed in the tubes.
A tube with a pink cap is coated with ethylenediaminetetraacetate (EDTA).
What is EDTA?
EDTA has an anticoagulant function by chelating with Ca ions that are essential for clotting. Because EDTA forms a complex with calcium, it is no longer available for clotting. EDTA causes swelling of the blood cells and platelets after a few hours. A blood sample with a purple cap should therefore be examined as soon as possible.
