Searching for hidden disease: study tests patients with mysterious pain

This French study aimed to find out how many patients with unexplained abdominal pain and neurological symptoms actually have acute hepatic porphyria, a rare metabolic disorder. Researchers tested 150 adults who had already gone through initial medical exams that didn't find a cause for their symptoms. The study used urine tests to look for specific chemicals that indicate porphyria, hoping to help patients get accurate diagnoses sooner and avoid lengthy diagnostic delays.
