This is often based on clinical signs and the recovery of eggs from the perianal skin. Sometimes adult worms can be seen passed in the faeces.

'''Tail rubbing''' is a frequent diagnostic feature.
'''Tail-rubbing''' accompanied by broken hair shafts, or excoriated skin on the rump or base of the tail is a frequent diagnostic feature. Donkeys do not, however, appear to demonstrate this behaviour as frequently as horses. The intense itching often leads to restlessness and impaired feeding, causing some loss of condition.

===Laboratory tests===
Unlike other nematode parasites of donkeys and horses, pinworm eggs are rarely observed in faecal samples due to the unique egg-laying behaviour of the females. However, O. equi eggs can be collected by pressing clear sticky tape onto the perianal skin and applying the tape to a glass slide for direct microscopic observation.
