Measuring physical and biochemical parameters with mobile devices

A test strip module for testing a sample with a mobile computing device distinct and separate from the test strip module, the test strip module comprising:

• a case comprising a top defining a sample channel between an exterior surface of the top and an interior surface of the top;
• a test strip in the case;
• a bottom cover closing an open bottom of the case, wherein the bottom cover defines:
• a light port;
• and
• a camera port opposite of the test strip, the camera port being laterally displaced from the light port;
• a position anchor extending down past a mating surface defined by the case or the bottom cover;
• and
• a fluid transfer film on the top abutting a sample collector defined by the exterior surface of the top and the sample channel;
• wherein
• the fluid transfer film abuts an open half of the sample collector and includes a hydrophilic layer adjacent to a bottom of the sample collector;
• and
• the sample channel is between the hydrophilic layer and the test strip.
