A low level of ferritin indicates iron deficiency is present in a body, explains Healthline. A diet low in iron and anemia both cause iron deficiency.
A high ferritin level may indicate that a person has a condition causing the body to store excessive amounts of iron, according to Mayo Clinic. It can also be a sign of liver disease, hyperthyroidism or rheumatoid arthritis.
Causes of a low ferritin level include chronic bleeding in the digestive tract, heavy menstrual bleeding, iron-deficiency anemia and problems absorbing iron, explains MedlinePlus. Ferritin is a protein that stores iron in the body.
In women, a normal ferritin level is between 12 and 150 nanograms per milliliter, while 12 to 300 ng/mL is normal for men, according to MedlinePlus. However, readings on the low end of these ranges do sometimes indicate too little iron in the blood.
Individuals suffering from low ferritin levels may exhibit signs of anemia and other conditions related to iron deficiency, according to Mayo Clinic. Ferritin is a protein that binds with iron and allows the body to store iron in the blood.
A normal ferritin level for men ranges from 12 to 300 nanograms per milliliter, notes MedlinePlus. Ferritin is a protein involved in iron storage. Medical professionals use the ferritin test as an indirect measure of how much iron is in the blood.
According to the Mayo Clinic, lower than normal ferritin levels are indicative that someone has an iron deficiency. Ferritin is a blood cell protein that contains iron.
Ferritin levels in the blood indicate how much iron is stored in the body, according to WebMD. Ferritin is a protein that binds to iron and is found in the liver, spleen, skeletal muscles and bone marrow. The small amount of ferritin found in the blood indicates the amount of iron in the body.
For men, the normal range for ferritin is 24 to 336 nanograms per milliliter, and for women, the normal range for ferritin is 11 to 307 nanograms per milliliter, explains Mayo Clinic. These are measured in standard units.
A ferritin blood test measures the level of ferritine in the body, explains MedicineNet. As ferritin is the major iron storage protein in the body, ferritin blood tests can indirectly measure iron levels. No special preparation is required before the blood test.
