Phlebotomy Colored Coded Tubes

Phlebotomy relies on various colored coded tubes to ensure accurate sample collection and testing. Each color represents a specific additive that serves a unique purpose in blood analysis. For instance, the NO ADDITIVE TUB is ideal for serum tests, whereas the SODIUM CITRATE TUBE is crucial for coagulation studies. The RAPID SERUM TUB is designed for quick assays, and the EDTA TUBE helps preserve cellular components for hematology tests. In addition, GEL SEPARATOR TUBES contain a gel that separates serum from cells after centrifugation, while HEPARIN TUBES are used for plasma determinations. The FLUORIDE (GLUCOSE) TUBE is specifically for glucose tests, preventing glycolysis. Understanding these tubes' functions not only aids in correct sample processing but also enhances the accuracy of lab results, ultimately improving patient care.
