3. red blood cells being destroyed faster than they can be produced.
investigating anemia:
several rountine investigations are used to diagnose anemia:
complete blood count (CBC), which gives numbers of all the cell types.
a blood smear, which examines the red blood cells' color and shape.
a test to check for low levels of vitamin b12 and folic acid.
a test to estimate the body's stores of iron.
a reticulocyte count to measure how many young cells the bone marrow is producing.
