Blue Top Sodium Citrate Vacutainers are specialized blood collection tubes designed for coagulation testing. These tubes contain a precise concentration of buffered sodium citrate (typically 3.2% or 3.8%), which acts as an anticoagulant by binding calcium in the blood sample. This prevents clotting and helps maintain the integrity of the sample for accurate coagulation analysis.
Sodium citrate vacutainers are commonly used in laboratory settings for tests such as Prothrombin Time (PT), Activated Partial Thromboplastin Time (aPTT), D-dimer, and other coagulation studies. The tubes are made of high-quality plastic or glass and feature a blue cap for easy identification. They are designed to ensure the correct blood-to-additive ratio, which is crucial for reliable test results.
