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).
