The Role of the Royal Blue EDTA Tube in Trace Element Testing
The royal blue EDTA tube is a specialized blood collection tube used primarily for trace element, toxicology, and nutritional studies. Unlike standard tubes, the royal blue top EDTA tube is manufactured with ultra-clean materials to avoid contamination, making it ideal for detecting very low levels of metals and minerals in the blood. It contains EDTA (Ethylenediaminetetraacetic acid) as an anticoagulant, which prevents the blood from clotting and preserves the sample for accurate analysis.
