It is best to fast for the anemia test as eating may have an effect on the results.
The anemia test is for Ferritin, Vitamin B12 and Folic Acid, and fasting is recommended because eating may affect the test results.
Anemia triple test is a routine test for anemic patients to check whether there is a decrease in the above three hematopoietic materials to rule out whether the anemia is caused by a decrease in the above hematopoietic materials.
If serum ferritin concentration is significantly reduced, it can be diagnosed as iron deficiency anemia, which requires iron supplementation treatment and more iron-rich foods such as animal offal; if serum folic acid or vitamin B12 concentration is reduced, it can be diagnosed as megaloblastic anemia, which requires supplementation of folic acid and vitamin B12 treatment.
However, if the three items of anemia are normal, other tests should be done to exclude blood system diseases. Specific recommendations under the guidance of a specialist.
