I have looked for info in my drug book and online and in this stack of books here, but I can't find the ever so simple answer to this question...
What is the normal range for iron saturation %?
Anyone that knows please please have mercy on my tired rear and tell me! I had to get assigned this patient of 100 unusual lab tests and this is the only one I am stuck on. Thanks a bazillion!
Are you talking about SaO2? Anything above 92 is generally ok with acceptable perfusion, unless an ARDS or COPD pt, they can have much lower. Make sure you don't have a low H&H, as a high SaO2 can be very deceiving.

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
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?
MU?????? is it MU??????? that funny little m thing?
it's late. :chuckle don't hold my ignorance against me. :chuckle
serum transferrin saturation
transferrin iron saturation
serum iron to tibc ratio
tfs = 100 x serum iron (ug/dl) / tibc (ug/dl)
15% to 55%
-chronic iron deficiency anemia
-third trimester of pregnancy
-hemochromatosis and other iron overload
-acute viral hepatitis
-aplastic anemia or sideroblastic anemia
this one is a foreign site... but it gives an explanation...........
hope this helps!!!
Thanks everyone! It was the percentage thingy that Christine gave. My patient's level was 5. I knew that it was probably low, but I didn't know how low!
