Diseases caused by human parasites remain on a worldwide basis among the principle causes of morbidity and mortality. Correct diagnosis of intestinal parasitic infection depends on proper collection, transport, detection and identification of parasites in stool specimens. Symptoms range from malaise to death. Treatment is dependent upon examining multiple stool specimens due to the erratic shed rates of some parasites.

Interfering substances-bismuth, barium (wait 7-10 days),
antimicrobial agents (wait 2 weeks), gall bladder dye
(wait 3 weeks after procedure).

10 grams or 10 mL fresh stool preserved in 10% formalin and Polyvinyl
Alcohol Transport or single Total-Fix(R) transport vial.

Place fresh stool in 10% formalin transport vial, as well as
PVA transport medium or single Total-Fix(R) vial, within 30
minutes of collection. Add stool to bring the liquid level to
the "fill to here" line on the vial. Mix well. Send specimen(s)
at room temperature in the same shipping container. If parasite
infestation is strongly suspected, collect at least 3 stool
specimens every other day, since a single specimen can be
negative. If Giardia is strongly suspected, please see
Giardia Antigen, EIA Stool, Test Code 8625.

Note: Urine may be submitted unpreserved for exam for
Schistosoma. Collect at mid day. Peak egg secretion occurs
between noon and 3 p.m. Do not submit first morning specimen.
In patients with hematuria, eggs may be found trapped in blood
and mucous in the terminal portion (last-voided portion) of the

Sputum: The specimen should be a deep expectorated sputum,
preferably collected in the early morning. A 24 hour sputum
collection is also acceptable. Submit in a sterile screw-capped
container, unpreserved or in 10% formalin to increase stability.
