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.
