Anemia Support Group
Anemia (or anaemia), which literally means "without blood," is a deficiency of red blood cells and/or hemoglobin. This results in a reduced ability of blood to transfer oxygen to the tissues, and this causes hypoxia; since all human cells depend on oxygen for survival, varying degrees of anemia can have a wide range of clinical consequences.

I lived in Europe, so I don't know what the values are. But I just had a blood test done, so I will know better.
Are your doctors trying to find out why your hemoglobin dropped so low?
