Ova and Parasite

Ova and Parasite Exam, Fecal (Immunocompromised or Travel History) should be used only in patients with appropriate risk factors (eg, immunocompromised, bloody diarrhea, persistent diarrhea [≥14 days], or chronic diarrhea [>30 days]). Even in the presence of these risk factors, specific pathogen testing is preferred, and recommended tests include Gastrointestinal Parasite and Microsporidia by PCR or Gastrointestinal Parasite Panel by PCR.
