Description

This K2EDTA microtainer is a small-volume blood collection tube specifically designed for the collection, transport, and processing of capillary blood from pediatric, geriatric, or critical care patients. The tube contains dipotassium EDTA (K2EDTA), a potent anticoagulant that works by chelating calcium ions to prevent blood clotting while preserving the original morphology of blood cells. Recognizable by its lavender color-coded closure, the microtainer features a wider-diameter reservoir to facilitate blood flow and an integrated collection scoop for ease of use. It typically holds a fill volume between $250\text{–}500 \mu\text{L}$ and is primarily used for hematology determinations, such as a complete blood count (CBC), blood typing, and lead testing.
