Patent ID: 8071051

Claim:
A disposable analysis cartridge capable of performing at least part of a blood sample measurement, comprising: two or more reagent storage reservoirs, a first one for storing a lysing reagent and a second one for storing a sphering reagent; a first flow sensor in fluid communication with the first one of the reagent storage reservoirs; a second flow sensor in fluid communication with the second one of the reagent storage reservoirs; a lysing on the fly channel in fluid communication with the first one of the reagent storage reservoirs; a sphering on the fly channel in fluid communication with the second one of the reagent storage reservoirs; and a first flow cytometry analysis channel structured to hydrodynamically focus a blood sample and to support flow cytometric measurements, the first flow cytometry analysis channel in fluid communication with and downstream of the lysing on the fly channel; and a second flow cytometry analysis channel structured to hydrodynamically focus a blood sample and to support flow cytometric measurements, the second flow cytometry analysis channel in fluid communication with and downstream of the sphering on the fly channel.
