Velvet consistently collects 5-6 drops of whole blood, resulting in approximately 180 μL, and separates the sample into its red blood cell and plasma components. Samples remain stable—and compatible with existing lab instruments— for up to 28 days at room temperature, while traditional blood collection tubes commonly used in phlebotomy are only stable for hours at room temperature.
