Glucose Test is used to measure the glucose level in one’s blood. Diabetes patients or persons who show signs of frequent urination, drastic weight loss, tingling of hands or feet or increased thirst will require glucose test in blood that will indicate whether the person has diabetes or not. High level of glucose in blood also known as hyperglycemia can indicate diabetes that can lead to heart disease, kidney failure, blindness, and developing other complications. If the glucose level in blood is lower than the normal also known as hypoglycemia then it can cause major health problems that include brain damage, if not treated.
High glucose levels may indicate kidney disease, pancreatitis, hyperthyroidism or pancreatic cancer. Lower blood glucose level may be a sign of Hypothyroidism, using too much insulin or other diabetes medicine and presence of liver disease. Also known as the fasting plasma glucose test (FPG), the patients need not eat anything for at least eight hours before this test. When the value of glucose test is between 70 and 100 milligrams per deciliter or mg/dL then it is considered normal. When the fasting blood glucose level is greater than or equal to 126 mg/dL and that is measured after taking into account 2 blood test then the person is considered to be diabetic.
