The ferritin test may be ordered, along with other iron tests, when a routine CBC shows that a person’s hemoglobin and hematocrit are low and their red blood cells are smaller and paler than normal (microcytic and hypochromic), suggesting iron deficiency anemia even though other clinical symptoms have not yet developed.
The ferritin test is ordered to assess a person’s iron stores in the body. The test is sometimes ordered along with an iron test and a TIBC to detect the presence and evaluate the severity of an iron deficiency or overload. This is a non-fasting blood test. Expect results in 1-2 business days.
