American Scientist reported, a Japanese imaging company Canon has developed a self-contained blood sampler and test strip that does the job very simply.
The device consists of an array of small needles about the size of the head of a toothbrush sealed behind a rubber membrane. The patient places his or her finger on the membrane and presses. The needles pierce both the membrane and the skin, drawing blood which flows towards a test strip where a chemical test takes place. When the patient removes his or her finger, the rubber membrane reseals, thereby keeping the sample clean while it is sent through the post for analysis.
Maybe it is considerably cheaper than visiting a health professional, but tasks such as taking blood samples are difficult for untrained people to perform.
