*Avoid practices that encourage the development of anthelmintic resistance
−
Faceal worm egg counts do not reliably detect horses infected with ''A.perfoliata''. A serological ELISA has been developed which has a sensitivity of 70% and a specificity of 95%(40) and a coproantigen capture ELISA also demonstrates promise (Kania).

Faceal worm egg counts do not reliably detect horses infected with ''A.perfoliata''. An ELISA to test for the host antibody response to tapeworms has been developed with a reported sensitivity of 70% and a specificity of 95%.<ref>Proudman, C.J, Trees, A.J (1996) Use of excretory/secretory antigens for the serodiagnosis of ''Anoplocephala perfoliata'' cestodosis. ''Vet Parasitol'', 61:239-247.</ref> Although this test is useful for detecting horses with a high intensity of infection, it measures past and current infection so must be interpreted in light of the anthelmintic history. More recently, a coproantigen capture ELISA has demonstrated some promise in a small sample of horses(Kania). Such tests may be used as part of a '''targeted strategic dosing''' programme for anthelmintic administration.
