Biologic fluid sample analysis cartridge

A biological fluid sample analysis cartridge, comprising:

• a collection port;
• at least one channel within the cartridge in fluid communication with the collection port;
• a passage in fluid communication with the at least one channel;
• and
• an analysis chamber mounted on a tray, which tray is mounted relative to the cartridge and selectively positionable relative to the passage in a first position where the analysis chamber engages a bolus of sample extending out from the passage to permit selective transfer of sample from the bolus to the analysis chamber;
• wherein the passage includes a first end and a second end, and which first end is in fluid communication with the at least one channel, and which second end is configured to permit the formation of a bolus of sample extending out from the second end;
• and
• wherein the at least one channel includes an initial channel in fluid communication with the collection port, and a secondary channel having a first end in fluid communication with the initial channel and a second end in fluid communication with the passage;
• and
• wherein the initial channel has a cross-sectional area sized such that sample travels by capillary force within the initial channel and the secondary channel has a cross-sectional area sized such that sample cannot travel by capillary force within the secondary channel.
