Abstract
The present invention provides systems, devices, kits, and methods for separating blood plasma or serum from whole blood. The present invention further provides systems, devices, and methods for separating a volume of blood plasma or serum from whole blood.
Claims20
A method of separating non-cellular components of a sample of blood from the cellular components of the sample of blood, the method comprising the steps of:
- providing a sampling membrane configured to receive and contain the sample of blood, the sampling membrane configured to retard a movement of the cellular components relative to a movement of the non-cellular components;
- and
- applying the sample of blood to a central portion of the sampling membrane such that the sampling membrane retards the movement of the cellular components relative to the movement of the non-cellular components and includes, after a predefined period of time from receiving the blood, a plurality of testing sites that each provide different concentrations of the cellular components and the non-cellular components.
