1. A method, comprising:
causing a barrier that separates a sample chamber from a dilutant chamber of a patient sample container to be actuated to automatically release dilutant stored in the dilutant chamber to be mixed with a patient sample stored in the sample chamber;
after the dilutant is mixed with the patient sample in the sample chamber, receiving a data signal representing multiple first light transmittance data generated when light is transmitted through the patient sample when the patient sample is exposed to a first magnetic field;
receiving a data signal representing multiple second light transmittance data generated when light is transmitted through the patient sample when the patient sample is exposed to a second magnetic field or the patient sample is no longer exposed to the first magnetic field;
determining a differential light transmission characteristic of transmitted light through the patient sample based on the multiple first light transmittance data and the multiple second light transmittance data;
identifying presence of a compound in the patient sample based on a characteristic of the differential light transmission characteristic;
calculating a compound characteristic based on the presence of the compound or a byproduct of the compound in the patient sample and the differential light transmission characteristic; and
generating an instruction to output the compound characteristic.
