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.
You will be offered the glucose tolerance test if the results from the glucose challenge test indicate that you may have gestational diabetes. The glucose challenge test (GCT) is routinely offered when you are between 24 and 28 weeks pregnant. The GCT does not diagnose gestational diabetes, it simply screens for it.he test is usually carried out when you're between 24 weeks and 28 weeks pregnant. Your midwife or doctor will let you know if you can eat and drink before the test or how long you need to fast before taking the test. You may need to go to a clinic to have the test or you may be in hospital.
