3 TUBES, EXP 2027
A Streck DNA-free tube, specifically the Cell-Free DNA BCT, is a specialized blood collection tube that stabilizes blood to prevent white blood cells from releasing their genomic DNA into the plasma, ensuring a pure sample of circulating cell-free DNA (cfDNA) for advanced tests like cancer screening, liquid biopsies, and prenatal screening, allowing for delayed processing and transport at room temperature. It preserves cfDNA for up to 14 days and circulating tumor cells (CTCs) for up to 7 days, simplifying logistics for research and diagnostics.
