Serum transferrin is an iron transport protein in the blood that helps determine the body's iron status: 

Iron deficiency: Serum transferrin levels can indicate iron deficiency, and transferrin saturation levels can be a sensitive indicator of functional iron depletion.                                                                                                                                                                                                                                               Anemia: Serum transferrin levels can help determine the cause of anemia. 

Iron metabolism: Serum transferrin levels can help examine iron metabolism
