Objectives: to examine the methods used to diagnose favism at Al-Rammadi Pediatric Hospital in adult patients who have a history of the condition.Patients and method: The investigation was conducted from January 1 to December 31, 2021. The group was then divided into two. Throughout the course of the trial, group 1 participants were all patients who were admitted to a pediatric hospital and diagnosed with favism. Any patients with a protracted history of favism who were met in routine medical practice throughout the trial period and gave his consent were also added to group 2 if they chose to participate.Results: A total of 41 patients were present; group 1 consisted of 20 men and 5 women, whereas group 2 consisted of 16 patients (13 men and 3 women). Group 1's diagnosis of favism was primarily clinical in the absence of sufficient test evidence. Of them, 11 had relatives who had suffered from favism, and four of them had alarmingly lengthy histories of the illness. One patient in group 2 had a potentially dangerous past history of favism, six had a family history of the disease, ten had a G6PD test completed, and seven of them had the disease confirmed. The ingestion of fava beans was resumed in the 14 patients who were left for a variety of reasons after Favism. Every instance in both groups occurred between the end of February to the end of April.
