1. A system for testing saliva to measure at least one substance or physiological parameter of a human or animal subject, the system comprising:
a handheld saliva testing device comprising a sensor slot and a display;
a sensor comprising:
a first end configured for insertion into the sensor slot of the handheld saliva testing device;
a second end configured for receiving saliva directly from the subject's mouth on the second end of the sensor while the first end of the sensor remains inserted within the handheld saliva testing device;
at least one microfluidic channel configured to direct saliva from the second end to the first end; and
an enzyme mesh embedded between a top layer and a bottom layer of the sensor, configured to facilitate movement of saliva along a length of the sensor; and
a computer processor coupled with the handheld saliva testing device to process initial data from the handheld saliva testing device to provide final measurement data describing the at least one substance or physiological parameter.
