Blood Collection Tube – All Types

Blood collection tubes are sterile, vacuum-sealed vials with color-coded caps indicating specific additives (like anticoagulants or clot activators) for different lab tests, allowing for precise sample collection for hematology (CBC), chemistry (glucose, electrolytes), coagulation (PT/APTT), and genetics (DNA) by preventing clotting or preserving components, with the specific additive determining the resulting sample (serum, plasma, whole blood) and required handling.
