Laboratory Findings
- There are no specific laboratory findings associated with whip worm infection.
- Chronic blood loss may demonstrate a iron deficiency anemia picture on peripheral smear examination with microcytic and hypochromic anemia.
The laboratory diagnosis of whip worm infection is done by demonstration of eggs on stool examination.
- Stool Examination - Microscopy : A stool examination for ova and parasites reveals the presence of whipworm eggs.
A: Trichuris trichiura egg (wet preparation). The diagnostic characteristics are:
- A typical barrel shape
- Two polar plugs, that are unstained
- Size: 50 to 54 µm by 22 to 23 µm
The external layer of the shell of the egg is yellow-brown (in contrast to the clear polar plugs). The egg is unembryonated, as eggs are when passed with the stool.
B: Trichuris trichiura eggs. Figures show side-by-side eggs with regular (white arrows) and larger (black arrows) size eggs.
C: Atypical Trichuris sp. egg.
