Whats meaning of low transferrin saturation?

Whats meaning of low transferrin saturation?

Iron deficiency: Until proved otherwise. The body has made protein, probably extra, to carry iron that isn't available. ...Read more

Receptor (Definition)

An organ, cell or molecule that accepts an outside signal and causes an internal change. Eyes receive light, touch receptors send messages to the brain when stimulated by pressure and estrogen receptors bind Estradiol causing responses of normal breast, ovary and uterus cells to rising and falling levels of the female steroid hormones. Most of the time "receptor" refers to one ...Read more

What does this mean as a blood test: transferrin?

What does this mean as a blood test: transferrin?

Transferrin is a…: …blood plasma protein that delivers 2 iron ions from absorption centers to all tissues, especially for the production of hemoglobin. Low tf may be a liver defect (where it's made) or a kidney problem allowing excessive loss. Decreased plasma tf can lead to iron overload diseases such as hemosiderosis. Increased tf binds free iron, leading to anemia. Discuss lab results with your doc. ...Read more

Is a transferrin saturation of 23% low for a man?

You're fine: 15-50% is a pretty good range for a man. Wondering why you asked, and glad you're taking a proactive approach to your health. ...Read more

Where do providers typically like to see iron and transferrin sat levels?

Where do providers typically like to see iron and transferrin sat levels?

Accurate lab results: All that matters is that the lab deliver results that accurately reflect what is happening with the patient. It's all about your health, not trying to keep numbers in range. If you're iron-deficient, we want to know right away to find the cause -- which may be a serious illness we can treat. If the trans-sat is high, we can address possible iron overload. No "decision level" replaces a dr's skill. ...Read more

Iron high at 178 (40-150), TIBC high normal at 439 (261-478). Sometimes both are high. What causes this? % transferrin sat 41; ferritin 50 (11-204)

Iron high at 178 (40-150), TIBC high normal at 439 (261-478). Sometimes both are high. What causes this? % transferrin sat 41; ferritin 50 (11-204)

Follow it: Serum iron can go high after taking a few vitamin-and-mineral tablets or eating a nice steak. There's no need to pay attention to a "high-normal TIBC" -- unless you're way-out-of-range it means nothing. Iron is often somewhat abnormal in folks with a mix of autoimmune diseases like you have, especially RA, but in your case, I'd be glad that there seems to be no problem. ...Read more

What is the definition or description of: transferrin?

What is the definition or description of: transferrin?

Carries iron: This protein is the major carrier of iron atoms in the blood. It tends to run high in iron deficiency and rather low when there's liver disease or bad longlasting infection. The percent of transferrin molecules ("saturation") that carry an iron atom is a good way of spotting iron deficiency or overload if the patient hasn't recently popped an iron pill. ...Read more

Any idea why my transferrin is dropping?

Any idea why my  transferrin is dropping?

Maybe: Low transferrin may be due to a malfunction of your live, rwhere it's made, or a kidney defect that allows excessive loss through your urine. Have your doctor fully evaluate the problem. ...Read more

My iron level is 59 , ubc is 325, tibc is 384 and transferrin sat is 15.4. Are these normal?

My iron level is 59 , ubc is 325, tibc is 384 and transferrin sat is 15.4. Are these normal?

Normal for females: Normal values for females are. Iron level 50to1170ug/dl.Tibc 250to370.Transferin saturation 15to50 percent.Your values look low normal but seem to me within normal range but you did not mention other values like hemoglobin which is important to know, if I have to guess it will be low normal and may meds to be followed. ...Read more
