Indications for performing a Ferritin Test include:
Evaluating an individual for possible iron-deficiency anemia; the signs and symptoms of which may include:
In such an individual, a routine hemogram/complete blood count would show low levels of hemoglobin (red pigment in the red blood cells) and hematocrit (the fraction of blood, made-up by RBCs). The red blood cells would appear smaller and paler, when examined under a microscope.
Evaluating an individual for possible overload of iron; the signs and symptoms of which may include:
These symptoms are caused by an accumulation of iron in the tissues and the resultant damage it causes.
Sample required: Blood
Process: Blood sample is drawn through a needle inserted into the vein (arm).
Preparation required: It is advised to fast for 12 hours, before getting tested. However, one may consume water during this period.
The normal blood levels of Ferritin, called the reference range for Ferritin, may vary slightly from lab to lab. Hence, most lab reports come with a reference range, which is used in that particular centre. One such reference range, in wide use, is per the following:
Low levels of Ferritin are found in individuals with iron deficiency.
High levels of Ferritin are found in individuals with iron overload, which may occur following multiple blood transfusions, or as a result of a disease called hereditary hemochromatosis.
The laboratory test results are NOT to be interpreted as results of a "stand-alone" test. The test results have to be interpreted after correlating with suitable clinical findings and additional supplemental tests/information. Your healthcare providers will explain the meaning of your tests results, based on the overall clinical scenario.
Ferritin levels can be increased by certain inflammatory conditions in the body. They may also be increased due to:
Certain medications that you may be currently taking may influence the outcome of the test. Hence, it is important to inform your healthcare provider, the complete list of medications (including any herbal supplements) you are currently taking. This will help the healthcare provider interpret your test results more accurately and avoid unnecessary chances of a misdiagnosis.
