Are there standard procedures for treatment of anemia?

Yes: The first step is determining a cause- either it can be low blood production or excess blood loss. Once a specific cause is identified the appropriate treatment plan is started by the treating doctor.

Yes, but your ?: Is really too general to answer accurately. The therapeutic approach taken depends upon the underlying cause, and causes of anemia are many and varied. They can result from impaired rbc production (eg., nutritional deficiencies, marrow infiltration, etc), hematoma, blood loss (gi bleed, hemorrhage, epistaxis, etc.), hemolysis, thalassemia, hemoglobinopathies, etc. More specifics would help.
