What does sodium citrate do in a vacutainer?
The BD Vacutainer Plus Citrate Plasma Tubes (UK Manufacturing Site) are sterile, plastic, evacuated tubes containing 0.109 molar sodium citrate as an anticoagulant intended to prevent whole blood from clotting before analysis, according to the FDA’s EUA letter.
What is buffered sodium citrate?
Product description. Buffered Sodium Citrate is used in clinical laboratories and blood banks as an effective anti-coagulant, usually in a ratio of 1:9 sodium citrate/blood. The citrate ion chelates calcium ions in the blood by forming calcium citrate complexes and disrupting the blood clotting mechanism.

Why is sodium citrate used for coagulation studies?
Background :Sodium citrate has been used as a coagulation test because factor V and VIII are more stable in a citrated specimen. Ethylenediaminetetraacetic acid (EDTA) has been used for the hematologic test because blood cells are preserved better in the EDTA specimen.
What is the purpose of sodium citrate in specimen collection?
The U.S. Food and Drug Administration (FDA) is aware the U.S. is experiencing significant interruptions in the supply of sodium citrate blood specimen collection tubes, also known as light blue top tubes (hereafter “sodium citrate tubes”), used for coagulation (blood clotting) testing because of an increase in demand …
Why 3.8 Sodium citrate is used in ESR?
The Sediplast Westergren and Streck methods use citrate as an anticoagulant, which results in dilution of blood and should correct the ESR owing to higher hematocrit values.
What is 3.8 Sodium Citrate?
Sodium citrate is used as anticoagulant to prevent blood from clotting. Dispense 0.5 ml of sodium citrate into test tube. Add 4.5 ml blood and mix gently by inversion of the stoppered tube. Sodium citrate is effective as an anticoagulant due to its mild calcium-chelating properties.
Why do we use Sodium citrate for coagulation tests?
How is Sodium citrate used as an anticoagulant?
SODIUM CITRATE 4% W/V ANTICOAGULANT SOLUTION USP is added to tubing sets during apheresis procedures. The solution is connected the tubing set in an apheresis collection. The recommended dose is determined by the apheresis device and metered into the tubing set by the apheresis device.
