Abnormal mean corpuscular volume can have various causes, ranging in severity from 'worrying' to 'generally fatal'. Finding the true cause means ruling out or confirming each possibility – in other words, diagnosis.
Diagnosis is usually a complex process due to the sheer number of possible causes and related symptoms. In order to diagnose abnormal mean corpuscular volume, we could:
|Metal Toxicity||5%||Ruled out|
|Parasite Infection||5%||Ruled out|
|Chronic Inflammation||3%||Ruled out|
|Sideroblastic Anemia||0%||Ruled out|
Mean Corpuscular Volume (MCV). Unit: Femtoliters; fL
Possible responses:→ Don't know
