My friend asked me “Do you know the amount of iron in one pint RBC?”  I had no idea. literally. As I googled, I couldn’t find a satisfactory answer.  I didn’t stop my search for this query and referred standard medicine textbooks, but in vain.

I then asked my professor the next day of my rounds and he said,”upon my experience, 1 unit of blood contains about 250 to 300 mg of iron”
