1. A toilet, comprising:
a urinalysis cassette, wherein a roll of contiguous strips subject to one or more color-change reagents is rolled onto a plurality of spools;
a first spool for distributing a pre-wound roll of contiguous strips;
a second spool for receiving and storing strips distributed from the first spool;
a light emitter, wherein light projects onto the strips;
a light-wavelength sensor, wherein colors on the strips are detectable;
a sensor, optical signal, and/or indicator to detect when the roll of contiguous strips are entirely transferred from the first spool to the second spool;
a urine-specimen-capture slit disposed within the toilet bowl;
a nozzle, wherein the nozzle is disposed within the urine-specimen capture slit;
a housing compartment for the urinalysis cassette located below a toilet bowl, the housing compartment comprising an orifice for receiving a urine sample, wherein the orifice is adjacent to the nozzle, wherein the nozzle is in fluid connection with the urine specimen-capture-slit and the orifice; and
a wireless communications network for transmitting urinalysis results as a digital readout.
