Description
The gold-standard Westergren method requires these specific ESR tubes for blood testing. This method relies on the exact internal diameter and length ($300\text{mm}$ long with a $2.5\text{mm}$ diameter) of the tube to ensure standardized results. Therefore, we manufacture these tubes to strict international specifications. This guarantees that your ESR test results are reliable and comparable across different laboratories.
In addition, these specialized tubes typically come pre-filled with a liquid $3.2\%$ sodium citrate solution. This acts as the necessary anticoagulant. Consequently, the tube’s vacuum ensures the precise blood-to-citrate ratio (typically 4 parts blood to 1 part citrate) maintains balance when you fill the tube to its marked level. This step is crucial for preventing coagulation and ensuring the test’s validity.
Precision and Compliance for Diagnosis
In fact, accuracy in the ESR test depends entirely on the correct preparation and measurement. These Westergren ESR tubes for blood testing feature clear, crisp volume markings (up to $200\text{mm}$). This allows technicians to easily read the sedimentation level after the mandatory one-hour period, thus simplifying result interpretation. Furthermore, the vacuum draw feature ensures the exact required volume of blood is collected, preventing concentration errors that can lead to false readings.
Therefore, choosing high-quality, compliant Westergren tubes is essential for detecting inflammation and monitoring diseases like temporal arteritis and rheumatoid arthritis.
Key Features for Accurate ESR Testing
These dedicated Westergren ESR tubes for blood testing combine compliance with convenience:
- Standardized Dimensions: $300\text{mm}$ length and $2.5\text{mm}$ internal diameter as required by the Westergren method.
- Pre-measured Anticoagulant: Contains the precise amount of $3.2\%$ Sodium Citrate solution.
- Vacuum Draw: Ensures the correct blood-to-anticoagulant ratio is achieved for test accuracy.
- Clear Graduation Markings: Allows for accurate reading of the sedimentation level up to $200\text{mm}$.
- Safety Cap: Features a secure cap for hygienic and safe handling during transport and processing.
Using these Westergren ESR tubes for blood testing is the foundation for an accurate and reliable inflammation assessment. Before inserting the tube into the stand, gently invert the sample 8-10 times to ensure the blood and anticoagulant are fully mixed.
