Test ID PARID Parasite Identification

Useful For

Gross identification of parasites (eg, worms) and arthropods (eg, ticks, bed bugs, lice, mites)

 

Detecting or eliminating the suspicion of parasitic infection by identifying suspect material passed in stool or found on the body

 

Diagnosing delusional parasitosis

 

Identifying ticks, including Ixodes (carrier of Lyme disease)

Reflex Tests

Test ID Reporting Name Available Separately Always Performed
BUG Arthropod Identification No, (Bill Only) No
WORMY Parasite Identification No, (Bill Only) No

Testing Algorithm

When this test is ordered, 1 of the 2 reflex tests above will be performed and charged based on whether the object is an arthropod or worm. For parasite artifacts and nonhuman parasites, the reflex test performed will be based on whether the object most closely resembles a worm (eg, mucus strands, food material, fibers) or an arthropod (eg, free-living insects).

Method Name

BUG: Arthropod and Artifact Identification

WORMY: Gross and Microscopic Examination

Reporting Name

Parasite Identification

Specimen Type

Varies

Specimen Type: Parasitic worms, insects, or mites

Container/Tube: Sterile container (10% formalin or 70% alcohol may be added if appropriate specimen type)

Specimen Volume: Entire specimen

Collection Instructions:

1. For scabies, submit skin scrapings on glass microscope slide. Cover with a clean slide and fasten down to transport. Rubber bands work well. Transport slides in a clean, dry container.

2. Submit whole worms and worm segments in 70% alcohol or formalin.

3. Submit arthropods (ticks, lice, nits, bed bugs, etc) in a clean, dry container.

Additional Information:

1. Specimen source and isolate description are required: morphology, tests performed, location of specimen, or other pertinent information.

2. Indicate reason for request.

Clinical Information

Infectious diseases are spread and caused by a variety of macroscopic vectors. A wide array of macroscopic parasites (worms and ectoparasites) and parasite mimics or artifacts may be submitted for examination and identification. It is important to promptly and accurately identify these specimens so that the ordering physician can appropriately treat and counsel the patient.

Reference Values

A descriptive report is provided.

Cautions

This test identifies a tick’s species, age, sex, and level of engorgement. It does not include analysis of ticks for the presence of Borrelia burgdorferi, the agent of Lyme disease.
