Test Code PARID Parasite Identification, Varies

Important Note

This is used by CMH for Scabies; the Cerner order is a REF MISC.


Necessary Information


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

2. Indicate reason for request.



Specimen Required


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 use a rubber band to hold the 2 slides together (do not tape). Place the slides in a clean, dry container for transport. If no slides are available at time of collection, the dry skin scraping can be submitted in a sterile container and will be placed on slide at time of examination. Skin scraping must be visible with the naked eye to be of a quantity sufficient for testing.

2. Submit whole worms and worm segments in 70% alcohol or formalin. Worms must be clean of stool to be suitable for examination.

3. Submit arthropods (ticks, lice, nits, bed bugs, etc) in a clean, dry container. Do not wrap in tape, gauze, or tissue that might obscure them during examination.

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, ticks, mites, free-living insects).

 

For more information see Parasitic Investigation of Stool Specimens Algorithm.
