People with a concussion need to be seen by a doctor. Most people with concussions are treated in an emergency department or a doctorâs office. Some people must stay in the hospital overnight for further treatment. Sometimes the doctors may do a CT scan of the brain or do other tests to help diagnose your injuries. Even if the brain injury doesnât show up on these tests, you may still have a concussion. Your doctor will send you home with important instructions to follow.
If the result is abnormal, it is typically followed up with a fasting blood glucose test or a GTT. Glucose blood tests are also used to screen pregnant women for gestational diabetes between their 24th and 28th week of pregnancy.
The initial 1-hour test is a glucose challenge test. If the results are abnormal, a glucose tolerance test is done. A glucose tolerance test, usually conducted in the 24 to 28 weeks of pregnancy, measures levels of sugar (glucose) in the mother's blood. Abnormal glucose levels may indicate gestational diabetes.
