SQ: MISCLM
Reporting Name
Parasite IdentificationUseful 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

Identifying ticks, including Ixodes species (the vector for 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, ticks, mites, free-living insects).
For more information see Parasitic Investigation of Stool Specimens Algorithm.

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.
