The assay which aids in the diagnosis of parasitic infections consists of four separate protocols; 1. Concentration which facilitates the recovery of protozoan cysts, coccidian cysts, helminth, eggs, and larvae. 2. Trichrome stained smears which identifies intestinal protozoa. 3. Modified Acid Fast Stain which identifies Cryptosporidium and Cyclospora. 4. Modified Trichrome Stain which identifies Microsporidia.

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

Note: tissue samples should be sent to pathology

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.
