6. Diagnosis of Folate Deficiency

To diagnose folate deficiency, the health care provider takes symptoms into consideration and checks the person’s medical history. They also perform a physical examination and draw blood.

The blood goes to a laboratory where technicians check the number of red blood cells present and test folate levels. They also check vitamin B12 levels. Deficiencies of folate and vitamin B12 often coexist and cause similar symptoms.4‘Folate Deficiency Anemia.’ Folate Deficiency Anemia | Michigan Medicine, www.uofmhealth.org/health-library/hw152337. If the provider suspects a digestive cause, they may order a barium study and other tests.2‘Folate-Deficiency Anemia.’ Johns Hopkins Medicine, www.hopkinsmedicine.org/health/conditions-and-diseases/folate-deficiency-anemia.
