Almost everyone has provided a blood sample at a certain point of life, but ever wondered why so many tubes?
Using current analytical technologies, several health indicators/analytes can only be obtained from blood and therefore giving a blood sample is inevitable. The collected blood sample needs to be processed almost immediately, otherwise it must be frozen until processed. Usually 4-5 different tubes of blood are withdrawn making the total volume close to 25 mL, which is quite a bit. However, there has not been a blood stabilizing technology that is able to stabilize multiple analytes.
The table below describes the tubes and additives currently used for processing blood samples. If genetic testing is involved even more blood tubes are needed, one for RNA stabilization, another for cfDNA and may be another for CTCs (in addition to what is shown in the chart).

Mawi DNA’s HemaSure whole Blood Stabilization Tube, BST, technology is tackling this issue allowing multiple analytes including DNA, RNA, cfDNA, and CTCs to be tested from as few as 1-2 tubes. While allowing for the samples to be transported at room temperature with up to 14 days transit time.
Would it be great if you just give 1 or 2 tubes of blood rather than 4-7 tubes?
