Product Name	Veterinary Sodium Citrate Blood Collection Tube
Product Image
Product Overview	The Veterinary Sodium Citrate Blood Collection Tube is designed for collection of anticoagulated blood samples used in coagulation testing for cattle, pigs, horses, goat-farming-equipment/" target="_blank" class="keylink">sheep, goats and other animals. The tube contains buffered sodium citrate, commonly 3.2% at approximately 0.109 mol/L, and is designed to maintain the required blood-to-anticoagulant relationship when filled to the specified draw volume. The citrate binds calcium ions temporarily and helps preserve coagulation factors for laboratory analysis. It is suitable for veterinary diagnostic laboratories, commercial livestock farms, breeding operations and herd health programs where PT, APTT, fibrinogen and related coagulation studies may be required. :contentReference[oaicite:1]{index=1}
Key Features	Designed for veterinary coagulation blood testing. Contains buffered 3.2% sodium citrate anticoagulant. Typical sodium citrate concentration is approximately 0.109 mol/L. Uses a controlled vacuum to draw the intended sample volume. Designed around a 9:1 blood-to-citrate mixing ratio when filled correctly. Light blue closure provides rapid visual identification of citrate coagulation tubes. Compatible with suitable vacuum blood collection needles and holders. PET plastic options provide good strength, chemical resistance and resistance to breakage. Available in multiple nominal draw volumes according to laboratory requirements. Suitable for PT, APTT and other routine coagulation studies. :contentReference[oaicite:2]{index=2}
Structural Components	Vacuum Tube Body: Clear plastic tube designed to maintain the specified internal vacuum. Sodium Citrate Additive: Buffered anticoagulant solution used to preserve coagulation factors. Light Blue Closure: Color-coded cap for citrate coagulation tube identification. Rubber Stopper: Allows penetration by a compatible blood collection needle while maintaining a closed system. Fill Indicator: Helps confirm that the tube has reached the required sample volume in applicable configurations. Identification Label: Provides space for animal ID, sampling date and laboratory information according to configuration.
Working Principle	After successful venipuncture, the vacuum tube is inserted into a compatible holder. The pressure difference draws blood automatically into the tube until the intended fill volume is reached. Sodium citrate binds calcium ions required for the coagulation cascade and thereby temporarily prevents clot formation. For standard 3.2% citrate coagulation tubes, the recommended proportion is approximately one part citrate to nine parts blood. Accurate filling is important because underfilling can alter the blood-to-anticoagulant ratio and affect coagulation test results. After collection, the tube should be gently inverted according to the tube instructions to mix the sample thoroughly without causing excessive agitation. :contentReference[oaicite:3]{index=3}

Use & Handling	Select a citrate tube with a suitable draw volume for the animal species, sampling site and required coagulation test. Inspect the tube before use and do not use damaged tubes or tubes with compromised vacuum. Perform venipuncture using appropriate veterinary restraint and aseptic technique. Allow the tube to fill to the specified level so that the correct blood-to-citrate ratio is maintained. Immediately after collection, gently invert the tube according to the manufacturer's instructions to mix blood with the anticoagulant. Vigorous shaking should be avoided. Samples intended for coagulation testing should be handled and processed according to the requirements of the diagnostic laboratory and test system. Used needles and contaminated collection materials must be discarded according to local veterinary biohazard and sharps-disposal requirements.
Product FAQ	What is a sodium citrate blood collection tube used for? It is mainly used to collect blood samples for coagulation studies such as PT, APTT and related veterinary tests. Why is 3.2% sodium citrate commonly used? Buffered 3.2% sodium citrate, approximately 0.109 mol/L, is widely used in coagulation tubes because it provides a standardized anticoagulant concentration for routine coagulation testing. Why is correct fill volume important? Citrate tubes depend on the correct blood-to-anticoagulant ratio. Underfilling or overfilling can change this ratio and may affect laboratory results. What is the normal blood-to-citrate ratio? Standard 3.2% citrate coagulation tubes are generally designed for approximately nine parts blood to one part citrate. Can these tubes be used for cattle and pigs? Yes. Appropriate citrate tubes can be used for cattle, pigs, horses, sheep, goats and other animals when the correct draw volume and veterinary sampling procedure are selected. Can different tube capacities be supplied? Yes. Multiple draw volumes and tube dimensions are available according to diagnostic requirements and project specifications.
