Blood processing has not changed in decades, but advanced analytical techniques only require a drop or two of blood. So why collect large tubes of blood? New technology allows a few drops of blood to be collected anytime and anywhere with little or no discomfort. The technology uses advanced membrane systems to pull the plasma from whole blood while leaving the blood cells behind. Rapid air drying stabilizes the sample in minutes for storage or shipping. Cooling and a source of power are NOT needed to prepare the blood sample for shipping.
