Vacuum clot activator tubes are used in hospitals and clinics for venous blood collection. The interior surface of the tube is coated with dried clot activators, such as silica particles, which accelerate blood coagulation upon contact.

Biochemistry
Serology
Hormone analysis
Immunology
Microbiology
Blood banks
Recommended Order of Tubes During Blood Collection
During blood collection, a specific sequence should be followed:
Additive-free tubes (red/yellow cap) for blood cultures
Citrate tubes (blue cap) for coagulation
Gel-containing tubes (red/yellow cap)
Heparin tubes (green cap)
Hemogram tubes (purple cap)
Oxalate-fluoride tubes (gray cap)
Post-Collection Guidelines
If blood is collected using trace element tubes or vacuum clot activator tubes:
Invert the tube gently 4–5 times
Label each tube with patient name, ID number, collection date, and time
Tubes should be kept upright for up to 20 minutes to allow for clotting before separation
Sample Preparation with Clot Activator Tubes
Collect double the amount of blood needed for the desired serum volume (e.g., 6 mL of blood for 3 mL of serum)
After blood is collected, gently invert the tube 4–5 times to activate the clotting agent
Leave the tube in an upright position for 60 minutes to allow proper clotting
If a gel-containing tube was not used, carefully transfer the serum into another properly labeled serum tube for testing or storage
Tube Handling Considerations
Always check the expiration date of the tubes. Expired tubes may lose vacuum and lead to cap failure
Fill the tube according to its indicated volume
Even though these tubes are single-use, verify that they are properly sterilized before use
