The Glucose – Random test is a blood test used to measure the blood sugar level at any time of the day, regardless of when the person last ate. It is typically used to diagnose diabetes or to monitor blood sugar levels in people with known diabetes. A high random glucose level may indicate that the body is not producing enough insulin or that the insulin it produces is not working effectively. This test is particularly useful for people who experience symptoms of high blood sugar, such as fatigue, excessive thirst, or frequent urination. It can also be used to diagnose gestational diabetes in pregnant women, a temporary form of diabetes that can develop during pregnancy. The random glucose test is a quick and easy way to assess blood sugar levels, but it may not provide as accurate information as fasting glucose or oral glucose tolerance tests, which require more specific timing and preparation.
