Etiology
- impaired production
- disorders of precursors
- infiltrative disease of the bone marrow
- lymphoma
- multiple myeloma
- other metastatic malignancy
- infection, granulomas
- osteopetrosis
- exogenous factors
- drugs or toxins, including alcohol
- vitamin B12 deficiency or folate deficiency
- viral infection
- increased destruction
- splenic pooling
Laboratory
- complete blood count (CBC) (pancytopenia, decrease in all cellular components)
- reticulocyte count low
- serum folate &/or serum B12 may be low
- serum iron, TIBC & serum ferritin
- hepatitis serology
- HIV testing
- serum protein electrophoresis & urine protein electrophoresis to r/o multiple myeloma
- flow cytometry (cytogenetic analysis)
Diagnostic procedures
Radiology
- ultrasound of abdomen to assess for splenomegaly
