The Sodium Citrate 1:4 Tube is a specialized medical-grade vacuum blood collection tube designed specifically for coagulation studies and plasma determination. By utilizing a precise concentration of sodium citrate as an anticoagulant, this tube prevents blood clotting by chelating calcium ions, ensuring that the coagulation factors remain intact and stable for critical laboratory analysis.
Engineered for high-precision diagnostics in clinical environments, our tubes feature a standardized 1:4 ratio of citrate to blood, meeting international laboratory requirements. The vacuum-driven system ensures accurate blood-to-additive ratios, reducing pre-analytical errors and providing medical professionals with reliable results for PT, APTT, and other essential hematology tests.

Frequently Asked Questions
The 1:4 ratio (one part citrate to four parts blood) is the international standard for coagulation tests. Incorrect ratios can lead to skewed results in PT and APTT tests, potentially resulting in misdiagnosis.
They should be stored in a cool, dry place away from direct sunlight, typically between 2-25°C, and kept within their original packaging until use to preserve the vacuum seal.
Yes, our Sodium Citrate tubes are designed to be universally compatible with all standard vacuum blood collection holders and needle systems used in modern clinical settings.
The light blue cap is a global color code identifying the tube as containing sodium citrate for coagulation studies, allowing lab technicians to quickly identify and prioritize these samples.
Samples should be gently inverted 3 to 4 times immediately after collection to ensure the sodium citrate is fully mixed with the blood to prevent micro-clots.
Yes, sodium citrate tubes are commonly used for Erythrocyte Sedimentation Rate (ESR) testing due to their ability to prevent clotting while maintaining cell morphology.
