A patient following a plant based vegan diet should supplement with:
A. iron
B Vit A
C. Vit B12
D. Folic acid
Vitamin B12
What test should be ordered next if lab results come back with
Low MCV
Low MCHC
High RDW
This is iron deficiency anemia so a ferritin level should be ordered
What test should be ordered next if lab results come back with
Low MCV
Low MCHC
Normal RDW
This is thalassemia minor so a hemoglobin electrophoresis should be ordered.
What test should be ordered next if lab results come back with
High MCV
Nml MCHC
High RDW
This is vitamin B12 or folate deficiency so a vitamin B12 and folate should be ordered
In anemia of chronic disease what will the hemogram show?
Everything is decreased except for a normal MCV and normal RDW
If a hemoglobin electrophoresis is ordered for thalassemia minor how often should it be ordered?
