Diagnosing an aerosolized attack or a food and water contaminant with ricin primarily depends on symptoms and the likelihood of such an exposure. In cases of an isolated ricin injection, diagnosis is extremely difficult. In addition, diagnostic testing is of limited value, because there are no definitive, widely available medical tests that can confirm ricin exposure. Nonetheless, in the case of possible exposure to ricin, the patient will most likely undergo a complete physical examination by a doctor. Sophisticated diagnostic tests (not widely available) can identify ricin in the body up to 24 hours after exposure.
