Ova and Parasites
- Sample Type
- Standard
- Fasting
- No
- Unit
- N/A
A microscopic examination used to detect the presence of parasites (protozoa or helminths) and their eggs (ova) in a stool sample. Within a Complete Stool Examination, this test is the gold standard for diagnosing parasitic infections like Giardia, Entamoeba, or Hookworm, which cause chronic diarrhea, abdominal pain, and malabsorption.
Why Context Matters
Parasites are shed intermittently. A single negative result does not rule out infection; three samples collected on different days are often required for definitive diagnosis. Recent use of antibiotics, antacids, or bismuth can also mask the presence of parasites.
Lab ranges are statistical averages, not biological laws. "Normal" for a 20-year-old male isn't normal for a 60-year-old female.
