It is found out that most of the
measurements for blood glucose concentration tests are done manually by using
the invasive method like blood drop and test. So, another approach with
non-invasive method is developed to measure blood glucose concentration by just
testing on urine using a colour sensor.
There is a wide range of urine reagent
strip tests available in the markets with many types of parameters can be
tested. Range of parameters that is available in the markets nowadays can be
from 1 to 11 parameters. These parameters are glucose, ascorbic acid, ketones,
protein, pH-value, blood, nitrite, leukocytes, specific gravity, bilirubin and
urobilinogen. The colour changes of the urine reagent strip after test can be
seen by naked. Unfortunately, we cannot get the accurate reading just by
looking at the colour changes of urine strip test. The level of diabetes cannot
be obtained accurately.
