iron deficiency anemia
"I am 14 years old. I went in for a physical, and had a routine blood panel. How did I get the results? An ambulance showed up at my house suddenly to take me to the hospital immediately. Apparently, my iron was 9, which is almost fatally low. I was given Venofer when I got there, and it helped tremendously. It quite possibly saved my life. I owe my life to Venofer."
