Clot Activator - Blood Collection Tube

Collecting blood from infants, neonates, and young children requires more than a smaller needle — it requires a tube engineered specifically for low-volume, low-trauma sample collection. The Nasmed Clot Activator Micro Pediatric Blood Collection Tube is designed to solve exactly this problem: it delivers accurate serum separation from micro-volume draws, reducing repeat pricks, minimizing hemolysis risk, and giving laboratories a reliable sample for biochemistry, serology, and immunoassay testing in pediatric patients.

As part of Nasmed Diagnostics’ complete range of blood collection consumables, this micro pediatric tube reflects our core focus: making diagnostic sample collection safer, faster, and more dependable for hospitals, NICUs, pediatric clinics, and diagnostic laboratories across India.

What Is a Clot Activator Micro Pediatric Tube?

A Clot Activator Micro Pediatric Tube is a small-volume, vacuum-based blood collection tube coated internally with a clot activator (silica-based) that accelerates coagulation. Unlike standard adult tubes, it is sized specifically for pediatric and neonatal draws, typically collecting between 0.5 ml to 1 ml of whole blood — enough for accurate testing without over-drawing from a small patient.

Once blood enters the tube, the clot activator triggers rapid clot formation. After centrifugation, this yields clean serum suitable for a wide range of diagnostic assays, including liver function tests, kidney function tests, lipid profiles, and hormonal assays.

Why Pediatric-Specific Tubes Matter?

Children and neonates have significantly lower total blood volume than adults. Over-collection during routine testing can contribute to iatrogenic anemia, especially in NICU settings where repeated blood draws are common. Using a correctly sized micro tube is a recognized best practice in pediatric phlebotomy, helping clinicians collect only what is clinically necessary while still obtaining a diagnostically valid sample.

Key Features of Nasmed Clot Activator Micro Pediatric Tube

• Micro-Volume Design: Optimized 0.5 ml–1 ml draw capacity for infants, neonates, and pediatric patients.
• Fast Clot Activation: Silica-based clot activator ensures rapid, complete clotting for quicker serum separation.
• Reduced Hemolysis Risk: Controlled vacuum draw minimizes red blood cell rupture, protecting sample integrity.
• Clear, Break-Resistant Barrel: Allows visual confirmation of adequate fill volume and clot formation.
• Secure, Color-Coded Cap: Red cap for easy identification and standardized lab workflow.
• Sterile & Single-Use: Each tube is individually sterilized to prevent contamination and cross-infection.
• Compatible with Standard Centrifuges: Fits routine lab centrifugation protocols without special equipment.
• Manufactured Under Quality Standards: Produced in an ISO-certified facility to ensure batch-to-batch consistency.

Comparison: Micro Pediatric Tube Range by Nasmed

Choosing the correct additive is critical in pediatric sample collection since each tube type is validated for a different category of tests. Use the table below to identify the right tube for your requirement.

Quick takeaway: If the test requires serum (most biochemistry and hormone tests), the Clot Activator tube is correct. If it requires whole blood for a CBC, use the K3 EDTA tube instead. Choosing the wrong additive can compromise results, so always match the tube to the ordered test panel.

Benefits for Laboratories and Hospitals

1. Fewer Repeat Draws: Correct micro-volume sizing reduces the chance of insufficient sample errors that require re-collection.
2. Better Patient Experience: Smaller needle-tube combinations reduce discomfort and distress for pediatric patients and their families.
3. Reliable Serum Quality: Fast clot activation shortens turnaround time (TAT) for reporting critical pediatric results.
4. Standardized Workflow: Color-coded caps and consistent design integrate easily into existing lab protocols.
5. Safety Compliant: Designed to align with recommended practices for minimal-volume pediatric phlebotomy.

Recommended Blood Collection Procedure

1. Confirm patient identity and select an appropriately sized needle/lancet for pediatric draw.
2. Perform venipuncture or capillary collection as per standard protocol.
3. Allow the tube’s vacuum to draw blood to the fill line — avoid over- or under-filling.
4. Gently invert the tube 5–6 times immediately after collection to mix the clot activator with the sample.
5. Allow the sample to clot at room temperature (typically 15–30 minutes) before centrifugation.
6. Centrifuge as per your laboratory’s validated protocol to separate serum for testing.

Frequently Asked Questions (FAQs)

Q1. What is the draw volume of the Nasmed Clot Activator Micro Pediatric Tube?

• The tube is designed to collect between 0.5 ml and 1 ml of blood, making it suitable for neonates, infants, and young pediatric patients who cannot tolerate large-volume draws.

Q2. What tests can be performed using this tube?

• This tube is used for tests requiring serum, including liver function tests (LFT), kidney function tests (KFT), lipid profile, thyroid panels, and other routine or specialized biochemistry assays.

Q3. How is this different from the K3 EDTA Micro Pediatric Tube?

• The Clot Activator tube produces serum and is used for biochemistry/serology testing, while the K3 EDTA Micro Pediatric Tube preserves whole blood and is used specifically for hematology tests like CBC.

Q4. Why is a pediatric-specific tube necessary instead of a standard adult tube?

• Children have much lower total blood volume than adults. A pediatric micro tube collects only the minimum sample needed for accurate testing, reducing the risk of excessive blood loss during repeated or routine testing.

Q5. How long does it take for the sample to clot?

• Typically, samples clot within 15 to 30 minutes at room temperature after proper mixing, though exact timing can vary slightly by sample and lab protocol.

Q6. Is this tube safe for neonatal (newborn) use?

• Yes. It is specifically designed for micro-volume collection scenarios common in NICUs and pediatric departments, where minimizing blood draw volume is a clinical priority.

Q7. Where can I buy Nasmed Clot Activator Micro Pediatric Tubes in bulk for my lab or hospital?
