The Lavender Top Tube: A Vital Tool in Blood Collection and Testing
The lavender top blood collection tube is one of the most commonly used tubes in clinical laboratories. It is easily recognized by its purple or lavender-colored cap, which indicates that it contains the anticoagulant EDTA (Ethylenediaminetetraacetic acid). This additive prevents blood from clotting, making the lavender top blood tube ideal for hematology tests. These include Complete Blood Count (CBC), blood typing, and hemoglobin analysis, which are crucial for diagnosing conditions like anemia, infection, and blood disorders.
