Laboratory Studies
- Microscopic stool examination for ova and parasites[2]
- Complete blood cell count
- Hemoglobin and hematocrit levels may be below or at the lower end of the reference range.
- The mean cell volume may be above or at the higher end of the reference range.
- Eosinophilia may be present.
- Peripheral smear
- Vitamin B-12 level
- Folate level
Imaging Studies
- No imaging studies are required to evaluate diphyllobothriasis, unless otherwise clinically indicated by the patient's presentation.
Other Tests
- Cases of diphyllobothriasis have been successfully identified using capsule endoscopy.[3] This procedure is painless and may provide useful adjunctive information for the treatment of this disease.
Procedures
- No procedures are required in the workup of diphyllobothriasis.
