Ferritin (Definition)

Ferritin is protein complex that binds iron and controls iron levels inside all of our cells. Low levels in the serum is a useful marker of iron deficiency. Macrophages are cells that contain large amounts of ferritin, and this that helps them scavenge RBC at sites of old hemorrhage. High serum ferritin levels occurs from macrophage activation and is a ...Read more

Maybe: You have low ferritin levels while the other labs are essentially normal. A low ferritin level maybe the earliest sign of low iron levels. It may fall before iron levels do. Other causes of low ferritin include hypothyroid levels. You should follow with your primary care doctor to make sure these other tests are normal. A course of iron therapy maybe indicated. ...Read more

My ferritin level (15) dropped low (from 152) and tibc (471) is high, but iron is normal (71) and hgb remains slightly high (17.5). Iron deficiency?

No: Your hemoglobin is high not low that is the most probalbe reason your ferritin is low i simply would check my hemoglobin and the other tests in 6 12 monthst. ...Read more

Iron Deficiency oral iron tx 1 year. Is it typical to see your ferritin levels to continue to drop as you build your iron stores? Ferritin is 3.9.

Re-evaluate: It is possible that you are not absorbing the oral iron properly as ferritin level of 3.9 is abnormally low. You may wish to discuss the option of receiving iron intravenously, with your doctor. For good health - Have a diet rich in fresh vegetables, fruits, whole grains, milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form. Practice safe sex. ...Read more

My 22 month daughter has been diagnosed with iron deficiency. Her iron level is 26 with a range of 50-170. Ferritin level is at 59 ng/ml with a range of 5-100 and TIBC is 398 mcg/dl with a range of 250-450. My concern is could she have chronic illness

Bleed vs diet: serum iron does not reflect the body's total iron stores. Ferritin is by far more important. The serum iron is useful for calculating the percentage of saturation of iron in the iron binding capacity (transferrin level). In your daughter's age group it usually is from inadequate iron in diet. However, chronic bleeding into the G.I. tract must be excluded by testing stool for blood. ...Read more

Likely: The best test for iron deficiency anemia (ida) is ferritin. Sometimes when there is inflammation (an possible associated anemia of chronic disease/inflammation, the ferritin may increase as an acute phase reactant). The "gold standard" for diagnosis is a bone marrow biopsy, but rarely needed. High platelets are also associated with ida. Treatment should improve platelets and ferritin. ...Read more

Recent labs showed high platelets (416), high iron (148), high tibc (475), but a low normal ferritin level (12). Is this iron deficiency?

Recent labs showed high platelets (416), high iron (148), high tibc (475), but a low normal ferritin level (12).  Is this iron deficiency?

Suspect so: If the serum iron is in micrograms/dl, then this is not high but within the normal range, as it can be in iron deficiency in which the patient has perhaps taken an iron tablet or eaten steak recently. If the units for TIBC are micrograms/dl, then TIBC is distinctly high and this speaks for iron deficiency in any case. Don't treat iron deficiency without seeking a cause. ...Read more
