1. A system comprising:
a cartridge comprising:
receiving cavities, a receiving cavity for receiving a portion of a test sample;
reagent cavities, a reagent cavity for receiving the portion of the test sample;
testing cavities; and
ductwork for interconnecting at least the receiving cavity, the reagent cavity, and a testing cavity, the reagent cavity being configured to receive the portion of the test sample via the ductwork, the ductwork having a smaller cross-sectional area than at least part of each of the receiving cavities, the reagent cavities, and the testing cavities; and
wherein each of the reagent cavities comprises a reagent or combination of reagents, the reagent cavities comprising at least:
a first cavity comprising a first reagent to activate coagulation; and
a second cavity comprising a second reagent to activate coagulation;

wherein the testing cavity is configured for use in measuring a viscoelastic characteristic associated with a liquid in the testing cavity, the liquid comprising a mixture of the portion of the test sample and the reagent in the reagent cavity; and
wherein negative pressure is applied through at least part of the ductwork to draw the portion of the sample out from a bottom of the receiving cavity and upwards into the reagent cavity.
