EDTA/Purple top Vacutainers

EDTA Purple Top Vacutainers – Anticoagulant Blood Collection Tubes

EDTA Purple Top Vacutainers are sterile, vacuum-sealed blood collection tubes designed for hematology testing. These tubes contain Ethylenediaminetetraacetic Acid (EDTA), an anticoagulant that prevents blood clotting by binding calcium ions. The EDTA ensures that blood samples remain in their original state, making them ideal for tests requiring intact blood cells and accurate hematological analysis.

Key Features

✔ Contains EDTA Anticoagulant – Prevents clotting and preserves blood cell morphology.
✔ Sterile & Vacuum-Sealed – Ensures sample integrity and prevents contamination.
✔ Color-Coded Purple Cap – Easily identifiable for hematology use.
✔ Available in Various Sizes – Different volumes to suit various testing requirements.
✔ Compatible with Automated Analyzers – Suitable for modern laboratory equipment.

Common Applications

1. Hematology Tests:

• Complete Blood Count (CBC) – Measures red blood cells, white blood cells, hemoglobin, and platelets.
• Blood Smears & Morphology Analysis – Used for detecting blood disorders.
• Hemoglobin & Hematocrit Testing – Determines oxygen-carrying capacity of blood.
• Erythrocyte Sedimentation Rate (ESR) Testing – Assesses inflammation in the body.

2. Specialized Tests:

• Blood Typing & Crossmatching – Important for transfusion compatibility.
• Molecular & Genetic Testing – Used in DNA extraction and PCR analysis.

How to Use

1. Draw the Blood Sample – Using a sterile needle and collection system.
2. Gently Invert the Tube – Mix the blood with EDTA by gently inverting it 8-10 times to prevent clotting.
3. Label & Store Properly – Ensure correct patient identification and store as required before testing.
4. Send for Laboratory Analysis – Processed using automated hematology analyzers or manual techniques.
