Claim 0:
1. A method for separating blood plasma from whole blood, the method comprising: receiving, by a first reservoir of a device, a sample of whole blood comprising red blood cells, the first reservoir comprising:
a collection region;
a channel fluidly connecting the collection region to an outlet; and
a constricted region; and
applying a centrifugal force to the device to separate the sample of whole blood into a first fraction and a second fraction,
the first fraction being located in the collection region and comprising blood plasma from which substantially all red blood cells have been removed,
the second fraction being located in a second reservoir of the device and

comprising blood plasma and red blood cells that have been removed from the first fraction by the centrifugal force,
the channel substantially being filled with the first fraction via capillary action responsive to termination of the centrifugal force, and
the constricted region inhibits the second fraction from entering the collection region.
