i found this in my lab test book.......
"laboratory and diagnostic test with nursing implications" by joyce lefever kee, p. 268
iron, total iron binding capacity (tibc)
normal range for serum iron for an adult is 50-150 mg/dl (not miligrams either. ... it's that funny m thing and i can't think of the name of it right now. :chuckle )
TIBC is 250-450 mg/dl (again with the m thing)
elderly is 60-80 mg/dl serum iron and <250 mg/dl for TIBC
average daily iron intake should be 10-20 mg (milligrams). TIBC measures the maximum amount of iron that can bind to the protein transferrin.
decreased levels of serum iron could be iron deficiency anemia, cancer of the stomach, intestine, rectum, breast; bleeding peptic ulcer; protein malnutrition; blood loss; burns.
decreased levels of TIBC could be hemochromatosis, anemias, hypoproteinemia, renal failure, cirrhosis, infections, GI cancers
drug influences could be cortisone preps, dextran, testosterone
elevated levels of serum iron could be caused by hemochromatosis, anemias, liver damage, thalassemia, lead toxicity
elevated levels of TIBC could be microcytic anemia, acute and chronic blood loss, polycythemia
drug influences could be from oral contraceptives
does this help?
