Blood protein that binds with iron and is important in its transport, is considered a sensitive indicator of protein deficiency. Transferrin
Which would be a better indicator of protein deficiency and why, Albumin or Transferrin? Why? Transferrin. It is synthesized in the liver, increases when iron stores are low and decreases when iron stores are high.
