How do you test for strongyloidiasis?
Strongyloides infection is best diagnosed with a blood test. Strongyloides infection may be diagnosed by seeing larvae in stool when examined under the microscope, but it might not find the worms in all infected people. This may require that you provide multiple stool samples to your doctor or the laboratory.
