Claim 6:
7. A system for detecting an infection in synovial fluid drawn from a patient, the system comprising:
a vial receptacle sized to receive a vial containing the fluid sample;
a light source disposed in the vial receptacle and operable to illuminate the fluid sample in the vial;
a vial optical sensor disposed in the vial receptacle and operable 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;
at least one immunoassay strip receptacle sized to receive a corresponding at least one immunoassay strip, wherein each at least one immunoassay strip includes a reagent configured to react with a corresponding at least one analyte substance and to generate light substantially within a wavelength range corresponding to the analyte substance when the immunoassay strip is in contact with the fluid sample;
at least one optical sensor associated with the at least one immunoassay strip receptacle and different than the vial optical sensor, the at least one optical sensor corresponding to the at least one analyte substance and oriented to detect light within the wavelength range corresponding to the one of the at least one analyte substance when the at least one immunoassay strip is inserted into the at least one immunoassay strip receptacle, wherein the at least one optical sensor is configured to generate an immunoassay electrical signal indicative of an intensity of light detected within the wavelength range corresponding to the one of the at least one analyte substance; and
a processor configured to receive the vial electrical signal and the 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 diagnose a presence or absence of a periprosthetic joint infection in the fluid sample based on the sensor data.
