A system, method, and apparatus for preparing an absorbent core for use in absorbent garments is disclosed. The sensor is prepared by immobilizing a probe material to a surface of the sensor, wherein the probe material is known to bind to the target nucleic acid. Conduits act as gateways for synchronization between the mobile electronic device and the plurality of content servers or computers. A compressor running indicator circuit is electrically connected between the \u201cS\u201d and the \u201cR\u201d terminals to indicate a compressor running condition.
