Short Answer
Lavender tubes contain a substance called EDTA, which is an anticoagulant that binds to calcium ions in the blood and prevents it from clotting.
When the specimen is placed in the lavender-top tube, the EDTA binds to the calcium ions and prevents the clotting of the blood.
The tube also contains a gel-like substance that helps to separate the blood cells from the serum, allowing for better collection of the sample.
The combination of EDTA and the gel-like substance in the tube helps to ensure that the sample is collected without clotting.
What are Lavender Tubes?
Lavender tubes are specialized specimen collection tubes used to collect and store blood samples for laboratory testing.
These tubes are typically a light purple or lavender in color and are filled with the anticoagulant EDTA, which prevents the blood from clotting.
This makes them ideal for collecting, storing, and transporting blood samples, as they can prevent the samples from clotting and preserve their integrity.
The tubes themselves have a special design that allows them to be easily sealed and opened.
They also have a rubber stopper at the top that helps to ensure the sample is securely sealed within the tube.
Additionally, the tubes are often labeled with instructions for proper handling and collection to ensure accurate laboratory results.
What Causes Clotted Lavender Tubes?
When it comes to lavender tubes, the primary cause of clotted samples is improper handling.
When handling lavender tubes, it is important to take special care to ensure that the samples are not subject to any contamination or other conditions that could lead to clotting.
The most common causes of clotted lavender tubes include: improper filling of the tubes, mixing of blood cells and platelets, and leaving the tubes open to the air for too long.
When filling lavender tubes, it is important to make sure the tubes are filled to the correct level.
If the tubes are not filled to the correct level, the blood may be in contact with air, resulting in the clotting process being activated.
Additionally, if the tubes are mixed too vigorously, the blood cells and platelets may be activated, resulting in clotting.
Finally, if the tubes are left open to the air for too long, the clotting process can be triggered.
It is important to handle lavender tubes properly to ensure accurate laboratory results.
This means avoiding mixing blood cells and platelets, filling tubes to the correct level, and not leaving the tubes open to the air for too long.
If these steps are followed, the chances of obtaining accurate results are significantly increased.
Mixing of Blood Cells and Platelets
The process of clotting in lavender tubes can be caused by the mixing of blood cells and platelets.
This occurs when the lavender tube is not filled to the correct level, as the sample may not be able to circulate freely.
The anticoagulant EDTA prevents blood from clotting, however, if the sample is not filled to the correct level, the platelets and cells can mix and cause the clotting process to be triggered.
When the blood cells and platelets mix, the platelets become activated and release substances known as clotting factors.
These clotting factors interact with each other to form a mesh-like substance known as fibrin, which causes the blood to clot.
It is important to ensure that the sample is filled to the correct level as this will prevent the cells and platelets from mixing and triggering the clotting process.
Additionally, if the tube is left open to the air for too long, the clotting process can be triggered.
This is because the anticoagulant EDTA can be broken down by the oxygen in the air, allowing clotting factors to become active and interact with each other to form fibrin.
Therefore, it is important to handle lavender tubes correctly to prevent the clotting process from occurring.
Not Filling the Tube to the Right Level
One of the most common reasons why lavender tubes clot is due to not filling the tube to the right level.
If the tube is not filled to the correct level, the anticoagulant EDTA may not have enough time to properly work and prevent clotting.
Additionally, if the tube is not filled enough, it can lead to a decrease in the number of cells and platelets present, which can lead to clotting.
To ensure accurate laboratory results, it is important to fill the lavender tube to the correct level.
It should also be noted that the tube should not be filled more than two-thirds full, as this can also lead to clotting.
Additionally, if the tube is not filled quickly enough, air bubbles can form, which can also trigger the clotting process.
To prevent this, it is important to fill the tube quickly and carefully.
Leaving the Tube Open to Air for Too Long
When it comes to ensuring accurate laboratory results, proper handling of lavender tubes is key.
One important factor to consider in the collection and storage of blood samples is the amount of time the tube is left open to the air.
This is because if the tube is left open too long, the clotting process can be triggered.
When a lavender tube is left open to the air, the blood cells and platelets in the sample can mix with the oxygen in the air and activate the clotting process.
This can happen even when the tube is filled to the correct level and the anticoagulant EDTA is present.
This is why it is important to minimize the amount of time the tube is left open to the air.
If the blood sample needs to be drawn for a prolonged period of time, it is recommended that the tube be capped and sealed as soon as possible and stored at a stable temperature.
This will help to minimize the amount of air that the tube is exposed to and, in turn, minimize the risk of the blood sample clotting.
Additionally, it is important to check the tubes for any signs of clotting before sending the sample off for laboratory tests, as this can affect the accuracy of the results.
By following these simple steps, you can ensure that the lavender tubes being used for collecting and storing blood samples are handled properly and are less likely to clot.
Handling Lavender Tubes Correctly
When handling lavender tubes, it is important to take the necessary steps to ensure accurate laboratory results.
The first step is to fill the tubes to the correct level.
If the tube is not filled properly, it can trigger the clotting process.
Additionally, it is important to ensure that the anticoagulant EDTA is mixed properly with the blood sample.
This helps prevent the blood cells and platelets from activating the clotting process.
Furthermore, it is important to not leave the tube open to the air for too long.
If the tube is exposed to air for too long, it can also trigger the clotting process.
To ensure that the lavender tube is filled correctly and the anticoagulant is mixed properly, it is essential to use aseptic technique when filling the tube.
This includes using gloves and a face mask, as well as wiping the tube with an alcohol swab to disinfect it.
Additionally, it is important to use a needle and syringe when filling the tube to reduce the risk of contamination.
Finally, it is important to use the tube as soon as possible after filling it to prevent the clotting process from being triggered.
By following the proper steps and taking the necessary precautions when handling lavender tubes, it is possible to ensure accurate laboratory results.
Taking the time to fill the tube correctly and using aseptic technique when filling it can help prevent the clotting process from being triggered.
Additionally, using the tube as soon as possible after filling it can also help ensure accurate results.
By taking the necessary steps, it is possible to ensure that the lavender tubes are handled correctly and the results are accurate.
Potential Consequences of Clotted Lavender Tubes
When lavender tubes clot, the blood samples become compromised and inaccurate results may be produced.
This can lead to incorrect medical diagnoses and treatment plans.
Additionally, clotted tubes can lead to delays in diagnosis and treatment, which can be dangerous for patients in urgent need of care.
Furthermore, if tubes are clotted and must be disposed of, they must be disposed of according to the laboratorys disposal protocol to ensure that the environment is not contaminated.
Clotted tubes may also be due to a malfunction in the tubes anticoagulant, EDTA, which can lead to costly repairs and replacements.
In some cases, complete system failure can occur, leading to significant downtime and a decrease in productivity for the laboratory.
Additionally, faulty tubes can lead to contamination of samples and inaccurate test results, which can have serious consequences for the patient and laboratory.
