A blood sugar test is an essential test for people going through severe conditions of diabetes. It helps to keep a check on the level of blood sugar in the body. It is an effective test for managing diabetes and identifying the high or low levels of blood sugar. Anxiety, depression, sweating, irritability, and shaking are some of the symptoms of low blood sugar levels. On the other hand, extreme thirst, headache, weakness, blurry vision, and increased vision are the symptoms of high blood sugar.
