What is BCT blood test?
What is BCT blood test?
Cell-Free DNA BCT is a blood collection tube available as a CE marked In Vitro diagnostic device or as a Research Use Only tube depending on region of use. The tube stabilizes cell-free DNA for up to 14 days at 6 °C to 37 °C* and CTCs for up to 7 days at 15 °C to 30 °C*.
What is a BCT Tube?
Streck Cell-Free DNA BCT® is a blood collection tube with a preservative stabilizing nucleated blood cells. This unique stabilization prevents the release of genomic DNA, allowing isolation of high-quality cell-free DNA.
What is in a Streck tube?
The Streck RNA Complete BCT is a direct draw blood collection tube that maintains the draw time concentration of cell-free RNA and extracellular vesicles, such as exosomes.
Do Streck tubes expire?
Because of the water retention properties of glass, Streck’s Cell-Free DNA BCT reagent remains a liquid even years past expiration (Figure 2). Poor vacuum retention and loss of moisture shortens the shelf life of PET plastic BCTs and can lead to inconsistent results as the product ages.
Where does cell-free DNA come from?
Cell-free DNA (or cfDNA) refers to all non-encapsulated DNA in the blood stream. A portion of that cell-free DNA originates from a tumor clone and is called circulating tumor DNA (or ctDNA). cfDNA are nucleic acid fragments that enter the bloodstream during apoptosis or necrosis.

Why is EDTA used for CBC?
Historically, EDTA has been recommended as the anticoagulant of choice for hematological testing because it allows the best preservation of cellular components and morphology of blood cells.
What Colour is EDTA tube?

How accurate is cell-free DNA?
Cell-free DNA screening can detect more than 99 percent of Down syndrome pregnancies and 97 percent of trisomy 18 pregnancies. It detects about 87 percent of trisomy 13 pregnancies.
How accurate is cell-free DNA test for gender?
The overall average sensitivity of using cffDNA to determine fetal sex is 96.6% and the overall specificity is 98.9%. These vary very little with trimester or week of testing, indicating that the performance of the test is reliably high.
