Claim 5:
6. A system configured to measure viscoelastic characteristics associated with a blood sample, the system comprising:
a cartridge comprising:
a first receiving cavity configured to receive a first part of the blood sample;
a second receiving cavity configured to receive a second part of the blood sample;

the second receiving cavity being separate from the first receiving cavity;
a first reagent cavity configured to hold at least one first reagent;
a second reagent cavity configured to hold at least one second reagent;
a first testing cavity configured to hold a first liquid that is based on the first part of the blood sample and the at least one first reagent, the first testing cavity being configured to enable performance of a first viscoelastic test based on the first liquid in the first testing cavity;
a second testing cavity configured to hold a second liquid that is based on the second part of the blood sample and the at least one second reagent, the second testing cavity being configured to enable performance of a second viscoelastic test based on the second liquid in the second testing cavity;

ductwork comprising:
a first duct fluidically connected between the first reagent cavity and the first receiving cavity;
a second duct fluidically connected between the first reagent cavity and the first testing cavity;
a third duct fluidically connected between the second reagent cavity and the second receiving cavity;
a fourth duct fluidically connected between the second reagent cavity and the second testing cavity;
the first receiving cavity being associated with a single testing cavity which is the first testing cavity, the first receiving cavity being devoid of reagent prior to receiving the first part of the blood sample, and the first receiving cavity having a larger volume than a portion of the ductwork that has a length equivalent to a length of the first receiving cavity;
the first reagent cavity having a larger volume than a portion of the ductwork that has a length equivalent to a length of the first reagent cavity, the length of the first reagent cavity comprising a dimension along a first axis connecting an inlet and an outlet of the first reagent cavity, and the length of the first receiving cavity comprising a dimension that is parallel to the first axis;
the second receiving cavity being associated with a single testing cavity which is the second testing cavity, the second receiving cavity being devoid of reagent prior to receiving the second part of the blood sample, and the second receiving cavity having a larger volume than a portion of the ductwork that has a length equivalent to a length of the second receiving cavity; and
the second reagent cavity having a larger volume than a portion of the ductwork that has a length equivalent to a length of the second reagent cavity, the length of the second reagent cavity comprising a dimension along a second axis connecting an inlet and an outlet of the second reagent cavity, and the length of the second receiving cavity comprising a dimension that is parallel to the second axis;

the at least one first reagent comprising a reagent that is in the first reagent cavity for mixing with the first part of the blood sample; and
the at least one second reagent comprising a reagent that is different than the at least one first reagent and that is in the second reagent cavity for mixing with the second part of the blood sample, the first viscoelastic test being independent of the second viscoelastic test.
