Iron must be bound to something because free iron is toxic: T/F
True
The two places that transferrin can pick up iron are through duodenal absorption and from neutrophils. T/F
False: from duodenal absorption and Macrophages
Transferrin saturation= serum Iron/ TIBC x 100. T/F
True
Transferrin is manufactured by the liver. If significant liver damage is present, the transferring level will be decreased. This will cause the transferrin saturation to decrease. T/F
False: Transferring decreases, the saturation increases
Anything that decreases serum iron (like IDA) or that increases the amount of transferring will decrease the transferring saturation. T/F
true
Many bacteria require iron, so in chronic disease, iron is locked away and bount to it’s storage form called ferritin. This is important because in anemia of chronic disease the ferritin will go up, because iron is being locked away to bacteria don’t have access to it. T/F
True
The duodenum usually absorbs 1-2mg/day of iron. One unit of transfused blood delivers 250mg of iron. People that get frequent blood transfusions can become iron overloaded. T/F
True
Conditions like thalassemia, that are characterized by ineffective erythropoiesis, cause increased amounts of iron to be absorbed, so the transferrin saturation will be increased. T/F
True
TIBC and Transferrin saturation are the same thing. T/F
False
