Trichuris trichiura is the human whipworm, a type of roundworm. Adults live in the large intestine. A stool finding can contribute to evaluating infection, but it cannot directly determine the number of worms or the degree of intestinal damage.

Why exposure and life cycle matter
Infection follows ingestion of infective eggs from contaminated soil, hands or food. Eggs passed in stool need time in the environment before becoming infective; simply detecting a target cannot determine when or where exposure occurred. [1]
What symptoms can and cannot tell you
Many infections cause no obvious symptoms. Heavier infections, especially in children, can cause diarrhea, abdominal problems and impaired growth; severe cases can involve rectal prolapse. These symptoms require a clinical assessment and should not be graded from a DNA quantity alone. [1]
What GI-MAP reports
The worm section includes a T. trichiura target. A detected finding is not a count of visible eggs or adult worms and does not replace assessment for complications. The clinician may use microscopy or other appropriate testing to clarify a result. [2]
A negative target is limited to the sample and assay. It cannot rule out every worm or every reason for persistent diarrhea, and it should not be used to dismiss significant symptoms.
Why treatment should be specific
Different parasites have different management needs. A general “parasite cleanse” is not equivalent to a clinician-selected treatment for confirmed whipworm. The follow-up plan should state what is being assessed and which method is suitable.
Common questions
Is whipworm the same as hookworm?
No. Hookworms are different parasites with different life cycles and clinical considerations.
Does a positive result show a heavy infection?
Not by itself. A targeted molecular result is not a validated adult-worm burden or severity measure.
