reported as "unclassified antineuronal IgG." If detected, newly identified autoantibody specificities may
be reported. Complex patterns that include non-neuronal elements may be reported as "uninterpretable."

Parasite Identification
Clinical Information: Infectious diseases are spread by a variety of vectors. Identifying the vector
and causative agent often involves visual examination of organisms.
Useful For: Gross identification of parasites (eg, worms), arthropods (eg, insects, spiders), and suspect
material passed in stool Identifying ticks, including Ixodes (carrier of Lyme disease)
Interpretation: A descriptive report is provided.
Reference Values:
A descriptive report is provided.
Parasitic Examination
Clinical Information: Diarrhea, malnutrition, anemia, and intestinal obstruction are some of the
consequences of infection with intestinal parasites. Protozoa may cause diarrhea and/or malabsorption by
elaborating toxins or by adhering to or invading the mucosa or by unknown mechanisms.
Cryptosporidiosis occurs as a self-limited moderate diarrhea in young children, especially daycare
attendees and their relatives. Helminths (worms) may obstruct the intestine, cause blood loss, or interfere
with the absorption of essential nutrients. Larvae or eggs may disseminate beyond the intestine and cause
tissue destruction and provoke inflammation. Parasitic protozoa and helminths of various types also may
inhabit the intestinal tracts of humans and animals without causing disease.
Useful For: Detection and identification of parasites: included are Giardia, Entamoeba histolytica
(amoeba), helminth eggs, protozoa, larval worms, and segments (proglottids) of tapeworms. See Parasitic
Investigation of Stool Specimens Algorithm in Special Instructions for other diagnostic tests that may be
of value in evaluating patients with diarrhea.
Interpretation: A positive result indicates the presence of the parasite but does not necessarily indicate
that it is the cause of any symptoms. Some strains of protozoa are nonpathogenic and some helminths
cause little or no illness.
Reference Values:
Negative
If positive, organism identified
