High blood sugar, cholesterol and uric acid are non-communicable diseases and are one of the causes of death in the world. Generally, this disease is very susceptible to be suffered by the elderly. One of the tests to monitor blood sugar, cholesterol, and uric acid levels is with an invasive disposable test kit. This method is inefficient because it causes the risk of infection, increases medical waste and is quite expensive. Real work students from Walisongo State Islamic University Semarang group 53 held a free examination in Krandon Village as an effort to carry out community service through appropriate technology in the health sector. Examination tools are made by lecturers and students using non-invasive methods (without injuring the body). Based on the results of student interviews with the community and health workers, this work program received a good response because the examination did not cause pain and helped reduce medical waste in the environment.
