Optimize Genetic Testing with Cell Free DNA Tubes
Cell Free DNA Tubes for Diagnostic Labs in India : Sterile, Preservative Stabilised, Bulk Supply Ready
Cell Free DNA Tubes Improve Genetic Testing Accuracy by preserving sample integrity in advanced diagnostics like liquid biopsy and NIPT. Standard EDTA tubes fail to stabilise circulating cell-free DNA, leading to contamination and unreliable results. Nasmed Diagnostic Pvt Ltd manufactures sterile Cell Free DNA Tubes with preservative chemistry that stabilises samples up to 14 days at room temperature, enabling safe transport and accurate testing for laboratories and healthcare centres across India.
Why Cell Free DNA Tubes Are Essential for Liquid Biopsy and NIPT Testing in Indian Diagnostic Labs
The most common question a lab procurement manager raises is straightforward. Why can’t a standard blood collection tube handle cfDNA testing? The answer lies in pre-analytical biology. After venepuncture, nucleated blood cells begin to lyse. Furthermore, this lysis releases high-molecular-weight genomic DNA into the plasma. As a result, the cfDNA fraction — which carries the tumour-derived or foetal signal — becomes diluted and analytically unreliable. A dedicated Cell Free DNA Tube for diagnostic lab prevents this entirely.
Nasmed Diagnostic Pvt Ltd incorporates a formaldehyde-free cell stabilisation preservative into each Cell Free DNA Tube. This preservative crosses the leucocyte membrane and crosslinks intracellular proteins. Consequently, white blood cell lysis is inhibited for up to 14 days at temperatures between 6°C and 37°C. Therefore, labs in Surat, Pune, Jaipur, and Nagpur can collect samples at peripheral collection centres and transport them to central reference labs without cold-chain dependency. Furthermore, the preservative does not interfere with downstream PCR amplification, NGS library preparation, or digital droplet PCR quantification — critical assurance for oncology diagnostic teams.
