1. A blood testing apparatus, comprising:

  • a laser source configured to produce a laser beam to create a wound from which blood flows;

    a housing;

    a plurality of test members configured to be positioned in the housing, the plurality of test members being coupled to an annular carrier with the annular carrier coupled to a locating device in the housing;

    at least one humidity cover positioned at at least one of the plurality of test members, the humidity cover being at least partially removable;

    electronics used for analysis, the electronics further including an evaluation device that provides for comparisons with previously stored measurements or evaluation data, the evaluation device configured to store a current test measurement;

    a display;

    an IR blocking filter; and

    a photodiode, the photodiode having a light detecting surface, the photodiode supported within a laser casing at a position that when a laser beam exits an output facet the IR blocking filter reflects a portion of the laser beam towards the photodiode at the light detecting surface such that the photodiode is adapted for detecting the laser beam from the IR blocking filter as a feedback for controlling a power output of an optical resonant cavity defined by the laser casing.
