To enable half-a-dozen departments in a hospital to study condition of the patient, more than half a dozen times blood has to be drawn from the patient. If one can just take a drop of blood and draw the conclusions, it is a tremendous advance.
Researchers in Bombay IIT's centre for excellence in Nano Electronics, have come out with a table top device which uses only a drop of blood of the patient. This kit can show whether a patient has a problem and depending on the condition of the heart the colour of the drop of blood changes. This is assumed to be useful even before ECG can predict the condition of the heart.
