Clinical Performance Metrics:

• 3 . Application

  ---

  
  

• Oncology & Liquid Biopsy – Detect tumor-derived cfDNA for early cancer screening, treatment response monitoring, and minimal residual disease (MRD) assessment with reduced sample degradation.

• Non-Invasive Prenatal Testing (NIPT) – Ensure high fetal cfDNA recovery for accurate aneuploidy and genetic disorder screening.

• 
  

  Ideal for hospitals, reference labs, and biotech R&D, our tubes bridge the gap between sample collection and precision analysis—delivering consistency from clinic to lab.

• Transplant Medicine – Monitor donor-derived cfDNA (dd-cfDNA) to assess graft rejection risk without invasive procedures.

• Infectious Disease & Sepsis – Improve pathogen detection in bloodstream infections through enhanced microbial cfDNA preservation.Longitudinal Studies & Biobanking – Stabilize samples for large-scale genomic research with room-temperature storage convenience.
