Ferritin Screening: What is Ferritin
Ferritin, composed of protein and iron, is the storehouse in the body for iron. The doctor will order this test to determine how much iron your body has stored i
n reserves for future use. This test is usually ordered because the doctor suspects that you have too little iron or you have too much iron in your body – both of which have health risks.
Ferritin Screening: Low Levels of Ferritin
Low levels of ferritin can indicate several different health issues. They can indicate either anemia, restless leg syndrome, or iron deficiency.
Anemia, indicated by low levels of ferritin, can be caused by low levels of iron or a reduction in iron. Symptoms of anemia include mild skin paleness, less pink in the lips and the nail beds, irritability, fatigue and dizziness with a rapid heartbeat. It is very important to have children showing these symptoms to get tested, according to the Nemours Foundation, as anemia can cause developmental delays and behavioral problems.
Ferritin Screening: High Levels of Ferritin
High levels of ferritin can occur in patients with hemochromatosis, inflammation, liver disease, infection, and certain types of cancer, such as lymphoma and leukemia.
Hemochromatosis is an inherited disease found mostly in Caucasians. Hemochromatosis interferes with the body’s ability to get rid of iron. Over time, there is a buildup of iron in the tissues and organs which can lead to the dysfunction and failure of several organs. Complications of this disease can lead to diabetes, heart failure, heart attack, arthritis and cirrhosis of the liver. Discuss with your doctor the ordering of the ferritin test if you are concerned with this genetic disease.
