Hand-held shirt-pocket portable medical diagnostic system for checking measurement of blood glucose, urea nitrogen, hemoglobin, blood components or other body qualities. The system includes the engagement of a disposable needle or lance probe package (12) which carries a chemical reagent strip (94) such as blood reacting chemistry. The system includes a pen structure (14) having a visual readout (18), a microcomputer, and photosensing circuitry (50, 52) which measures the change of color of the blood reacting chemistry of the disposable probe package. The pen also includes a spring arrangement (42, 44) for actuating a needle or lance (90) into the skin for transferring blood from a finger or other area to the chemical reagent strip. A disposable probe structure package includes configurations for transferring of the blood to the reagent strip or the reagent strip to the blood. |
