Medimec EDTA K3 (Green bottle)

**Composition:**

• **EDTA (Ethylenediaminetetraacetic Acid) K3**: The primary anticoagulant used in the collection tube. It is present in a potassium salt form (potassium EDTA) to prevent blood coagulation.
• **Buffering Agents**: May include substances to maintain pH stability.
• **Preservatives**: Sometimes included to prevent microbial growth, although this is less common in blood collection tubes.
• **Plastic or Glass Tube**: The collection tube is typically made of either plastic or glass, designed to withstand the vacuum necessary for blood collection.

**Indications:**

• **Hematological Tests**: EDTA K3 is primarily used for complete blood counts (CBC), blood smears, and other hematological analyses where whole blood is required.
• **Blood Banking**: It is used in blood donation and transfusion settings to preserve the integrity of blood samples.
• **Molecular Testing**: Suitable for DNA and RNA extraction, as it prevents clotting and preserves cellular components.
• **Clinical Chemistry**: While not as common as serum tubes, it can be used for certain plasma tests where anticoagulation is necessary.

**Usage Instructions:**

1. **Collection**: Blood should be drawn using a sterile technique into the EDTA K3 tube.
2. **Mixing**: Gently invert the tube 8-10 times immediately after collection to ensure thorough mixing of blood with the anticoagulant.
3. **Storage**: Samples should be stored at room temperature or refrigerated, depending on the specific tests to be performed.

**Precautions:**

• Ensure that the tube is not expired and is properly sealed before use.
• Avoid hemolysis during blood collection and handling, as it can affect test results.
