Benefits of Ammonium Heparin in Blood Collection Tubes: Preventing Clotting, Easy to Use, Reliable Anticoagulant
Summary
- Ammonium Heparin is commonly used in some blood collection tubes to prevent clotting and ensure the integrity of the sample.
- It works by binding to calcium ions in the blood, which are necessary for the blood to clot.
- Ammonium Heparin is preferred over other anticoagulants in certain situations due to its reliability and ease of use.
Introduction
When you go in for a blood test or any other type of blood work, you may notice that the phlebotomist uses different types of blood collection tubes. These tubes are designed to preserve the blood sample and prevent clotting, which can affect the accuracy of the results. One common Anticoagulant used in some blood collection tubes is ammonium Heparin. In this article, we will explore why ammonium Heparin is used in some blood collection tubes and the benefits it provides.
What is Ammonium Heparin?
Ammonium Heparin is a form of Heparin, a naturally occurring Anticoagulant that prevents blood from clotting. It is made by sulfating Heparin, a substance derived from animal tissues. Ammonium Heparin is commonly used in blood collection tubes because of its ability to bind to calcium ions in the blood, which are necessary for the blood to clot. By binding to these calcium ions, ammonium Heparin prevents the blood from clotting, ensuring that the sample remains intact for testing.
How Does Ammonium Heparin Work?
Ammonium Heparin works by inhibiting the action of thrombin, a key enzyme in the blood clotting process. Thrombin is responsible for converting fibrinogen, a blood protein, into fibrin, which forms a mesh that holds platelets together to form a clot. By inhibiting thrombin, ammonium Heparin prevents the formation of fibrin and clotting of the blood sample.
In addition to inhibiting thrombin, ammonium Heparin also binds to antithrombin III, a protein in the blood that helps regulate the clotting process. By binding to antithrombin III, ammonium Heparin enhances its ability to inactivate thrombin and other clotting factors, further preventing clot formation.
Benefits of Ammonium Heparin in Blood Collection Tubes
There are several benefits to using ammonium Heparin in blood collection tubes:
Prevents Clotting
- One of the primary benefits of using ammonium Heparin is that it prevents the blood sample from clotting, ensuring that the sample remains intact for testing.
- Clotting can affect the accuracy of the Test Results and make it difficult to obtain a VALID sample, so using an Anticoagulant like ammonium Heparin is essential for reliable testing.
Easy to Use
- Ammonium Heparin is easy to use and does not require any special handling or preparation, making it a convenient choice for medical professionals.
- Simply adding the blood sample to a tube containing ammonium Heparin is enough to prevent clotting and preserve the sample for testing.
Reliable Anticoagulant
- Ammonium Heparin is a reliable Anticoagulant that has been used in blood collection tubes for many years with proven success.
- It is preferred over other anticoagulants in certain situations due to its effectiveness and ease of use.
Comparison to other Anticoagulants
While ammonium Heparin is a popular choice for blood collection tubes, there are other anticoagulants that are used for the same purpose. These include EDTA (ethylenediaminetetraacetic acid) and citrate. Here is a brief comparison of these anticoagulants:
EDTA
- EDTA is a chelating agent that binds to calcium ions in the blood, preventing clotting in a similar way to ammonium Heparin.
- It is commonly used for hematology tests and is particularly effective at preserving cell morphology.
Citrate
- Citrate works by binding to calcium ions and inhibiting coagulation factors in the blood.
- It is often used for coagulation studies and tests that require plasma samples.
Conclusion
Ammonium Heparin is a valuable Anticoagulant that is commonly used in blood collection tubes to prevent clotting and ensure the integrity of blood samples. Its ability to bind to calcium ions and inhibit key enzymes in the clotting process make it an effective and reliable choice for medical professionals. By understanding the benefits of using ammonium Heparin in blood collection tubes, you can appreciate the importance of this Anticoagulant in preserving the accuracy of blood tests and other diagnostic procedures.
