Multi-Sample Blood Collection Needles (Pen Needles)
View Details
Features
How it works: Clot activator tubes contain the additive of clot activator, which accelerates blood coagulation and reduces fibrin formation.
- Additive filling: The clot activator is sprayed on the inner wall of the tube. It will help the blood and clot activator to mix thoroughly.
- Operation notice: Invert the tube 6-8 times immediately after blood collection.
- Minium time before centrifugation:30 minutes after collection.
- Centrifugation instructions:1300g-2000g for 10minutes at 25℃ room temperature.

Application
Clot activator tube is used for routine biochemical, immunological, drug testing, HIV testing, tumor markers and other serum immunological tests, treatment Drug monitoring.
Biochemical tests:
- Liver Function: Evaluates liver condition. Markers: ALT, AST, TBIL, ALB; assess liver injury and metabolism.
- Renal Function: Evaluates kidney condition. Markers: Cr, BUN, UA; assess renal filtration and excretion function.
- Myocardial Enzymes: Markers: CK, LDH; auxiliary diagnosis of myocardial injury.
Immunological tests:
- Viral Hepatitis: Hepatitis B five-item test (including HBsAg, etc.), hepatitis A / hepatitis C antibodies.
- Infectious Diseases: Treponema pallidum antibody (TP), human immunodeficiency virus antibody (HIV).
- Tumor Markers: Alpha-fetoprotein (AFP, liver cancer), carcinoembryonic antigen (CEA, gastrointestinal tumors), CA125, CA199, etc.
Why this product is chosen?
Compared with plain tubes, clot activator tubes accelerate blood coagulation and shorten specimen turnaround time (TAT) in hospitals.
Frequently Asked Questions (FAQ)
A: Silica serves as a clot activator. It facilitates rapid coagulation of blood samples across a broad temperature range and prevents secondary precipitation of fibrin.
A: After blood collection, invert the tube 6-8 times immediately. Wait at least 30 minutes after sampling before centrifuging.
A: Fibrin strands observed in serum are primarily caused by incomplete blood coagulation. Recommended operations to avoid this issue:
- Gently invert the tube 6–8 times immediately after blood collection.
- Allow samples to stand for at least 30 minutes to achieve complete coagulation prior to centrifugation.
- Keep samples at proper room temperature during clot formation.
