Powder EDTA K2 Anticoagulant For Blood Collection , Soluble With Water

In the fields of medical testing and biological science research, EDTA dipotassium anticoagulant is widely used for the collection and preservation of blood samples. However, many people have doubts about whether it is toxic or not. We should have a correct understanding of its characteristics and pay attention to relevant usage and storage precautions during use.

Chemical Structure and Properties of Potassium EDTA

EDTA dipotassium, also known as ethylenediaminetetraacetic acid dipotassium, is a chelating agent. Its unique structure endows EDTA dipotassium with strong chelating ability for metal ions, especially calcium ions, making it play a crucial role in anticoagulant processes. EDTA dipotassium has relatively stable chemical properties and is not easily decomposed at room temperature and pressure. It can exist in the form of ions in aqueous solution and form stable complexes with metal ions. This stability ensures that it does not undergo self decomposition or transformation during the anticoagulant process, thereby producing toxic by-products. For example, during the blood sample collection process, EDTA dipotassium rapidly binds to calcium ions in the blood, forming a stable complex that prevents blood clotting, while maintaining its own chemical structure and not causing harm to blood components.

Widely used in clinical testing

In clinical testing, EDTA dipotassium anticoagulant is a commonly used anticoagulant for blood routine testing and other items. Medical staff use large amounts of blood collection tubes containing potassium EDTA to collect blood samples from patients every day. Long term clinical practice has shown that blood samples collected using EDTA dipotassium anticoagulant have not been found to have adverse effects caused by anticoagulant after testing and analysis. Both the observation of blood cell morphology and the detection results of various blood indicators were not affected by the toxicity interference of EDTA dipotassium.

Key points of EDTA dipotassium anticoagulant

1. The Importance of Adequate Anticoagulation

The key to preparing whole blood test specimens is sufficient anticoagulation. After blood collection, the blood collection tube should be reversed 5-8 times as soon as possible to prevent the formation of small blood clots. Especially when the temperature of the blood collection environment is higher than 25 ℃, the mixing of blood and EDTA dipotassium must be timely and sufficient, otherwise it can easily lead to blood coagulation or local coagulation. This not only affects the quality of the specimen, but may also lead to deviations in subsequent test results.

2. Limitations on Inspection Time

It should be noted that EDTA salt anticoagulation is not irreversible anticoagulation. Therefore, the EDTA anticoagulant test tube should be tested within 24 hours after blood collection, otherwise it may cause errors in the test results. The storage time of EDTA anticoagulant specimens varies under different conditions: white blood cell count can be stored for 48 hours at 4 ℃, and not more than 24 hours at 23 ℃; Platelet count can be stored for 24 hours at 4 ℃. Strictly adhering to these time limits is an important prerequisite for ensuring the reliability of inspection results.

3. Control of anticoagulant dosage

Anticoagulation requires sufficient EDTA, but excessive EDTA may cause morphological changes in blood cells. Therefore, it is particularly important to accurately control the amount of EDTA dipotassium added. When producing and using blood collection tubes containing EDTA dipotassium, it is necessary to strictly follow the standard specifications to ensure accurate dosage of anticoagulants, guarantee the integrity of blood cell morphology, and enable the test results to truly reflect the blood condition.

The precautions during use are not derived from toxicity

1. Prevent accidental ingestion

Although EDTA dipotassium itself is non-toxic, attention should still be paid to preventing ingestion and eye contact during use. This is not because it is toxic, but for safety and hygiene considerations. Firstly, as a chemical reagent, EDTA dipotassium is not a food, and ingestion may stimulate the gastrointestinal tract, causing discomfort symptoms such as nausea and vomiting, which are caused by foreign substances stimulating the gastrointestinal tract.

2. Properly stored

Potassium EDTA needs to be stored properly, generally in a dry, cool, well ventilated place, away from direct sunlight and high temperature environments. The main purpose is to maintain its chemical stability and anticoagulant properties, and prevent it from decomposing or deteriorating due to environmental factors. If stored improperly, it may lead to a decrease in its anticoagulant effect and affect the quality of blood sample testing, but this is not related to toxicity.
