1. A method of making a test cartridge for measuring an analyte or property of a liquid sample, the method comprising the steps of:
- (a) molding a housing comprising a first substantially rigid zone and a second substantially flexible zone, wherein said housing has a top portion and a bottom portion separated by a hinge region wherein the top portion forms a top portion of a conduit and the bottom portion forms a bottom portion of said conduit, and said substantially rigid zone has at least one sensor recess;
(b) inserting a sensor into the at least one sensor recess;
(c) folding said housing at said hinge region; and
(d) sealing said housing in a closed position, wherein said sealing forms the cartridge, and the cartridge comprises said conduit over at least a portion of said sensor.

20. A sample analysis cartridge, comprising:
-
(a) a housing having a sample entry orifice for receiving a fluid sample wherein said housing has a top portion and a bottom portion separated by a hinge region; (b) a holding chamber disposed between the sample entry orifice and a capillary stop for forming a metered sample therebetween, wherein the capillary stop is formed of opposing housing portions and a substantially flexible portion disposed therebetween to seal said opposing housing portions in a liquid-tight manner; and (c) a conduit disposed between the capillary stop and a sensor and being configured to deliver the metered sample from the capillary stop to the sensor. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27)
