Verified step by step guidance1
Identify the purpose of sodium citrate in blood collection tubes. Sodium citrate is an anticoagulant, which means it prevents blood from clotting.
Understand the different types of blood collection tubes and their additives: Red top tubes typically contain no additives and are used for serum collection. Green top tubes contain heparin, another anticoagulant. Purple top tubes contain EDTA, which is also an anticoagulant.
Recognize that blue top tubes are specifically used for coagulation tests and contain sodium citrate as the anticoagulant.
Consider the role of sodium citrate in stabilizing and preserving blood samples for accurate coagulation testing.
Conclude that sodium citrate is used in blue top tubes due to its anticoagulant properties, which are essential for coagulation studies.
