Claim 17:
18. A system for measuring analytes for an infection in synovial fluid drawn from a patient, the system comprising:
a vial receptacle sized to receive a vial containing a fluid sample;
a light source disposed in the vial receptacle to illuminate the fluid sample in the vial;
a vial optical sensor disposed in the vial receptacle to detect light scattered by white blood cells in the fluid sample and to generate a vial electrical signal indicative of an intensity of the light detected;
a first immunoassay strip receptacle sized to receive a first immunoassay strip having a first reagent configured to react with a first substance as a analyte for a periprosthetic infection and to generate light substantially within a first wavelength range when the first immunoassay strip is in contact with the fluid sample;
a first optical sensor configured to detect light in the first wavelength range when the first immunoassay strip is inserted into the first immunoassay strip receptacle and to generate a first immunoassay electrical signal indicative of the intensity of light detected within the first wavelength range;
a second immunoassay strip receptacle for holding a second immunoassay strip having a second reagent configured to react with a second substance as a second analyte for a periprosthetic infection and to generate light substantially within a second wavelength range when the second immunoassay strip is in contact with the fluid sample;
a second optical sensor configured to detect light in the second wavelength range when the second immunoassay strip is inserted into the second immunoassay strip receptacle and to generate a second immunoassay electrical signal indicative of the intensity of light detected within the second wavelength range; and
a processor configured to receive the vial electrical signal, the first immunoassay electrical signal, and the second immunoassay electrical signal as sensor data, and to communicate the sensor data to a communications interface, wherein the processor in communication with the communications interface is configured to analyze the sensor data and diagnose the presence or absence of a periprosthetic joint infection in the fluid sample based on the sensor data.
