EDTA Tube

The EDTA Tube is a specialized blood collection tube used in clinical laboratories and healthcare settings for the collection and preservation of whole blood samples. It plays a crucial role in maintaining sample integrity and ensuring accurate diagnostic testing.

Definition: The EDTA Tube, also known as an ethylenediaminetetraacetic acid tube, is a vacuum-sealed tube that contains EDTA, an anticoagulant substance. It is designed to inhibit blood clotting by chelating calcium ions, thus preserving the blood sample in its native form for various laboratory analyses.

Materials: The EDTA Tube is commonly made of high-quality plastic, such as polypropylene or polystyrene, which is compatible with blood collection and storage. The tube’s stopper is made of synthetic rubber or silicone to maintain an airtight seal.

Common Specifications: The EDTA Tube typically has a standardized volume capacity ranging from 2 to 10 milliliters. It is available in different colors to signify the specific laboratory test requirements, such as lavender or purple tops. The tube features a vacuum system that enables the collection of precise blood volume.
