Product Description
EDTA K2 Blood Collection Tubes serve as specialized containers for clinical and laboratory hematology testing. Each tube comes pre-coated with a precise amount of dry EDTA (dipotassium salt) anticoagulant, which prevents collected blood from clotting. These tubes ensure accurate cell morphology and counts. They work well for complete blood counts, blood typing, erythrocyte sedimentation rate (ESR) tests, and various hematology assays. You will find them in hospital laboratories, health check-up centers, research institutes, and public health facilities.
Usage Instructions
Preparation
Check the tube’s packaging integrity and expiration date before use.
Choose the correct volume: common sizes include 2 mL, 3 mL, 4 mL, and 5 mL.
Wear sterile gloves and a mask to keep the blood collection area clean.
Venous Blood Collection
Follow standard venipuncture procedures. Attach a vacuum blood collection adapter to the blood collection needle.
Insert the tube into the needle assembly; vacuum pressure will draw blood into the tube. Remove the tube promptly when it fills. Avoid leaving the tube in place too long, which could alter cell morphology due to prolonged EDTA contact.
Gentle Mixing
Immediately after drawing blood, invert the tube gently 8–10 times to mix EDTA and blood thoroughly. This ensures full anticoagulation. Do not shake vigorously; vigorous motion can damage blood cells.
Centrifugation or Storage
To run tests other than serum assays, complete them or centrifuge within 2 hours of collection. Typical centrifugation conditions: around 3000 rpm for 10 minutes (adjust per lab protocol).
If you cannot test immediately, store the tube at 2–8 °C but use it within 24 hours. Prolonged storage can compromise cell morphology and count accuracy.

Precautions
Do Not Freeze/Thaw Repeatedly
Once you open a tube, use it promptly. If you need to store blood long-term, separate plasma or cell pellets rather than keeping whole blood in the tube. Repeated freeze-thaw cycles can damage cells and skew results.Avoid Direct Sunlight
Do not expose tubes or collected samples to direct sunlight or high temperatures. Heat accelerates the degradation of certain blood components and affects test accuracy.Not for Coagulation Assays
Because EDTA chelates calcium, these tubes disrupt clotting factor activity. Do not use them for prothrombin time (PT), activated partial thromboplastin time (APTT), D-dimer, or other coagulation tests. Use dedicated coagulation tubes for those assays.Label Samples Clearly
Immediately after collection, label the tube with patient information, collection time, and department. Clear labels prevent sample mix-ups.Follow Laboratory Safety Protocols
Handle tubes according to your facility’s biosafety rules. During centrifugation, balance tubes and avoid tilting to prevent accidents.
