Non-Pyrogen Blood Collection Tubes (G Test & GM Test)

Product Overview

Manufactured under an ISO 13485-certified quality management system with dedicated cleanroom process controls, XINLE Non-Pyrogen Blood Collection Tubes deliver an essential pre-analytical solution for clinical microbiology, intensive care units (ICU), and infectious disease research.

Pyrogens—especially bacterial endotoxins derived from Gram-negative cell walls—are notorious for triggering false-positive results in sensitive microbial assays. Conventional blood tubes do not guarantee pyrogen-free standards. Our tubes undergo specialized raw material purification, environmental bio-burden control, and strict batch-release endotoxin testing to guarantee an ultra-low endotoxin level of ≤0.005 EU/mL, ensuring uncompromised diagnostic accuracy.

Key Features & Biological Advantages

• Ultra-Low Endotoxin Threshold (≤0.005 EU/mL): Endotoxin content is strictly controlled at ≤0.005 EU/mL, eliminating background endotoxin interference in high-sensitivity diagnostic workflows.
• Eliminates False-Positive Fungal Results: Essential prerequisite for G Test and GM Test workflows, preventing exogenous pyrogen contamination from skewing clinical decisions.
• Completely Closed Vacuum System: Evacuated closed-tube design supports direct-draw collection, safe transportation, and processing, minimizing biohazard exposure and external air contamination.
• Comprehensive Additive Formulations: Available in three dedicated configurations (Red-No Additive/Clot Activator, Green – Sodium Heparin, Yellow – Gel + Clot Activator) to accommodate whole blood, plasma, and serum testing.
• Strict Quality Control Beyond Standard Norms: Produced under proprietary manufacturing standards covering raw material screening, mold decontamination, and cleanroom air filtration.
• Trusted by Leading Clinical Institutions: Extensively deployed in major tertiary hospitals and diagnostic centers for early invasive mycosis intervention.

Clinical & Diagnostic Applications

Non-Pyrogen Blood Collection Tubes are the gold standard for high-sensitivity infectious disease diagnostics and endotoxemia evaluations:

• G Test [(1-3)-β-D-Glucan Detection]: Early diagnosis and surveillance of deep invasive fungal infections (e.g., Candida, Aspergillus, Pneumocystis jirovecii, Fusarium spp., excluding Cryptococcus and Zygomycetes).
• GM Test [Aspergillus Galactomannan Antigen]: Early detection of invasive aspergillosis (IA), recognized as a vital microbiological criterion in international clinical guidelines.
• Combined G Test & GM Test Assays: Combined testing provides exceptional diagnostic performance, achieving a diagnostic specificity up to 98.3% and a positive predictive value (PPV) of up to 90%.
• Bacterial Endotoxin Testing: Rapid diagnosis of Gram-negative bacterial sepsis, bacteremia, and endotoxemia in critical ICU patients.
• Specialized High-Sensitivity Clinical Research: Cell therapy, cytokine release assays, and biobanking requiring strict pyrogen-free integrity.

How to Use Non-Pyrogen Blood Collection Tubes

Follow these clinical handling steps to ensure pyrogen-free specimen integrity:

1. Aseptic Venipuncture: Perform venipuncture using a sterile, single-use venous blood collection needle.
2. Blood Draw: Fill the tube to its designated vacuum draw volume.
3. Mixing (If Applicable):
   Red Cap (Plain): Allow to stand upright for natural clotting (do not invert).
   Green Cap (Heparin) & Yellow Cap (Gel): Gently invert the tube 5 to 8 times immediately after draw to mix additives thoroughly.
4. Closed Transport: Keep tubes sealed at all times and transport directly to the specialized microbiology or clinical testing laboratory.
