How does a Schilling test diagnose Hunter's glossitis?

Dr. Jeanne Morrison, PhD
Family Practitioner

Rather than diagnosing Hunter's glossitis, a Schilling test often helps to diagnose its root cause, pernicious anemia. During a Schilling test, your doctor will give you excess amounts of vitamin B12 and monitor your body to see how it reacts. If you urinate the amount you were given, that means your body can absorb B12 and you do not have pernicious anemia. Less B12 in your urine shows your body's inability to absorb the vitamin and, consequently, the presence of pernicious anemia. The presences of pernicious anemia often results in Hunter's glossitis.
