History and clinical signs are often used as a presumptive diagnosis, but a post mortem examination of a sick bird (which will be sacrificed for this purpose) is undertaken to confirm this. Gross lesions on the caecum and mid intestine are stereotypical of coccidiosis, but mucosal scraping for microscopic examination should be taken to identify coccidia with certainty.<br>

== Treatment and Control ==
Control of coccidia in turkeys, like broiler chickens, is intensive. Poults will be fed a prophylactic anti-coccidial drug for the first 7- 8 weeks of life and then removed from this usually two weeks prior to slaughter so no residues are present in the meat. Approved prophylactic drugs include amprolium, monesin and halofuginone.
Some farmers, primarily in the USA, are trying an innoculation for poults from the age of 1- 7days. this is spread in the water and a mild infection of coccidiosis then ensues. It is then hoped these birds will develop and immune response, so the use of continued drugs is not then needed. This program has been used with moderate success at this current time.
Should an outbreak occur which requires treatment, amprolium or some sluphonamides can be given to the flock via the water supply; often with moderate effect, hence prevention is better than treatment in this case.
