1. A system comprising:
a cartridge body comprising multiple fluid channels, a fluid channel among the multiple fluid channels comprising:
a measuring chamber for receiving a test sample;
a mixing chamber for holding at least one reagent and for receiving the test sample from the measuring chamber, the mixing chamber being in fluid communication with the measuring chamber;
a testing chamber for receiving a liquid that is based on a mixture of the test sample and the at least one reagent, the testing chamber being in fluid communication with the mixing chamber;
a first pressure port in fluid communication with the measuring chamber and configured to provide first pressure along a fluidic path to the measuring chamber to enable the measuring chamber to receive the test sample;
a second pressure port in fluid communication with the mixing chamber and configured to provide second pressure along a fluidic path to the mixing chamber to enable mixing of the test sample and the at least one reagent, the first pressure being in an opposite direction to the second pressure;
a vent port; and
conduits fluidically connecting the measuring chamber, the mixing chamber, and the testing chamber, each of the measuring chamber, the mixing chamber, and the testing chamber having a three-dimensional structure that is expanded relative to each of the conduits;
a heating element to apply heat to at least part of the cartridge body;
wherein the testing chamber is arranged to enable a test on the liquid received in the testing chamber, the test for measuring a viscoelastic characteristic of the liquid; and
wherein one fluid flow to the measuring chamber is based also on a state of the vent port.
