Serum ferritin testing is a low-cost, readily available, and minimally invasive method for assessing body iron stores. However ferritin levels may be elevated due to a variety of other causes including obesity, infection, inflammation (as an acute phase protein), chronic alcohol intake, liver disease, kidney disease, and cancer.
The ferritin levels measured usually have a direct correlation with the total amount of iron stored in the body. However, ferritin levels may be artificially high in cases of anemia of chronic disease, where ferritin is elevated in its capacity as an inflammatory acute phase protein and not as a marker for iron overload.

The goal is to maintain ferritin levels to < 1000 µg/L. [ citation needed ] Currently, two iron chelators are available in the US, deferoxamine for intravenous use and deferasirox for oral use. A third chelating agent is available, deferiprone , but it has limited utility in MDS patients because of a major side effect of neutropenia.
The ideal is to increase the body's iron deposits, measured as levels of ferritin in serum, with the aim of reaching a ferritin value between 30 and 100 ng/mL. Another clinical study has shown an increase in ferritin levels in those taking iron compared with others receiving a placebo . [ 11 ]
Iron can be stored in ferritin as ferric iron due to the ferroxidase activity of the ferritin heavy chain. [28] Dysfunctional ferritin may accumulate as hemosiderin, which can be problematic in cases of iron overload. [29] The ferritin storage iron pool is much larger than the labile iron pool, ranging in concentration from 0.7 mM to 3.6 mM. [25]
Higher levels of omega-6 fatty acids often found in ultraprocessed foods may interfere with the immune system’s fight against cancer cells, a new study says.
Tumor markers can be molecules that are produced in higher amounts by cancer cells than normal cells, but can also be produced by other cells from a reaction with the cancer. [ 2 ] The markers can't be used to give patients a diagnosis but can be compared with the result of other tests like biopsy or imaging.
Acute myeloid leukemia (AML) is a cancer of the myeloid line of blood cells, characterized by the rapid growth of abnormal cells that build up in the bone marrow and blood and interfere with normal blood cell production. [1]
