Diagnosing the disease is done by the sudden onset of the symptoms. Later, bloodwork is done in infected pigeons while other diagnostic tests and scans are done to gauge the level of tissue damage done in internal organs. As dozens of pigeons die after an outbreak in the loft, an autopsy can confirm the lesions.
