Clinical signs and season are enough to make a presumptive diagnosis.  

Clinical signs and season are enough to make a presumptive diagnosis.  

A faecal egg count should be performed, however, these often return with the result of zero eggs (as clinical signs are seen after 11-12 days whilst the prepatent period is 15 days). ''Nematodirus'' species eggs, including'' N. battus'', are much larger than [[strongyle]] eggs. They are brownish in colour and have straight sides. Bloods should be taken. With this disease, blood pepsinogen levels are normal, which is useful for ruling out the differential diagnosis of [[Ostertagiosis and Trichostrongylosis - Sheep|Ostertagiosis]]. A post-mortem examination can be carried out on any sheep that may have succumbed to the disease. Findings at necropsy would include enteritis and the presence of >10,000 adult worms (examine male worms to identify species) .
