Patent attributes
An apparatus suitable for measuring at least one plasma analyte in plasma extracted from a whole blood sample within the apparatus is provided. The apparatus can be adapted for insertion into a slot in a meter, which can preferably perform at least spectroscopic or biosensor measurement. The apparatus comprises a whole blood flow path, which begins at the inlet opening of the apparatus, and terminates at a vent or a suction chamber. Included in the blood flow path is a flow-through filtration chamber. The filtration chamber comprises at least one membrane separating a blood compartment from a plasma compartment. The apparatus further comprises a plasma flow path, which begins at the plasma compartment and terminates at a vent or a suction chamber. The plasma flow path includes a plasma analyte signal providing means. The signal is transmitted to a processor in the meter for preparing analyte measurements.
