Agary Sodium Citrate Blue Top Vacuum Blood Collection Tube

The Agary Sodium Citrate Vacutainer is a vacuum blood collection tube intended for collecting blood specimens used in coagulation testing. Sodium citrate acts as an anticoagulant by binding calcium, helping prevent the collected blood from clotting before laboratory analysis. Blue-top sodium citrate tubes are routinely used for coagulation investigations such as Prothrombin Time (PT), International Normalized Ratio (INR), Activated Partial Thromboplastin Time (APTT), fibrinogen and appropriate coagulation-factor assays. Standard coagulation tubes typically use 3.2% sodium citrate with a 1:9 citrate-to-blood ratio. The vacuum collection system enables venous blood to be drawn directly into the tube when used with a compatible blood collection needle and holder, making it suitable for hospitals, diagnostic centres, medical laboratories and blood collection facilities.
