Blood collection tubes are essential tools in medical diagnostics, and among them, 10ml EDTA purple top tubes are widely used for hematological testing. These tubes contain Ethylenediaminetetraacetic acid (EDTA), an anticoagulant that prevents blood clotting by binding calcium ions. This ensures accurate test results for complete blood counts (CBC), blood typing, and other hematology tests.
At EDTA Tube, we specialize in high-quality blood collection tubes, including 10ml EDTA tubes with purple tops, designed for reliability and precision. In this comprehensive guide, we’ll explore their uses, benefits, best practices, and more to help healthcare professionals optimize their blood collection processes.
What Are 10ml EDTA Purple Top Tubes?
10ml EDTA purple top tubes are sterile, vacuum-sealed blood collection tubes containing K2EDTA or K3EDTA as an anticoagulant. The purple top indicates their specific use in hematology testing. These tubes are essential for:
- Complete Blood Count (CBC) – Measures red blood cells (RBCs), white blood cells (WBCs), hemoglobin, and platelets.
- Blood Smear Preparation – Ensures proper cell morphology analysis.
- Molecular Diagnostics – Used in DNA/RNA extraction for genetic testing.
- Blood Bank Procedures – Essential for blood grouping and cross-matching.

Benefits of Using 10ml EDTA Purple Top Tubes
Prevents Blood Clotting Effectively
EDTA binds calcium ions, inhibiting coagulation pathways. This ensures accurate hematology results, as clotted samples can lead to false readings.
Maintains Cell Morphology
Unlike other anticoagulants, EDTA preserves cell integrity, making it ideal for blood smear examinations.
Standardized for Hematology Testing
The 10ml volume is optimal for multiple tests, reducing the need for additional draws.
Compatible with Automated Analyzers
These tubes work seamlessly with CBC machines, ensuring fast and reliable lab processing.

Using 10ml EDTA Tubes
Proper Blood Collection Technique
- Fill the tube to the marked line (10ml) to maintain the correct blood-to-anticoagulant ratio.
- Invert the tube 8-10 times immediately after collection to mix EDTA evenly.
Storage and Handling
- Store at room temperature (15-25°C) and avoid freezing.
- Process samples within 4-6 hours for best results.
- Learn more about Proper Handling & Storage of EDTA Tubes.
Avoiding Common Errors
- Underfilling or overfilling can alter test accuracy.
- Delayed mixing may lead to microclots.

FAQs
Can I use 10ml EDTA tubes for glucose or chemistry tests?
Nope. EDTA interferes with certain chemical analyses. For glucose or serum tests, use gray or red-top tubes instead.
What’s the difference between EDTA K2 and EDTA K3?
EDTA K2 is usually preferred for hematology because it causes less cell shrinkage compared to K3. Always check your test requirement.
Is there a specific angle or position for storing EDTA tubes?
Flat and upright is best. Avoid stacking them at weird angles or under pressure.
What happens if the tube is underfilled or overfilled?
It can lead to incorrect blood-to-anticoagulant ratios, skewing the results. Always follow the fill guide.
Can EDTA tubes be reused?
Absolutely not. These are single-use only and should be disposed of safely after use.
