The urine test, which detects elevated levels of compounds called porphyrins, costs $50 to $100. Heyer said the test would become less expensive if used frequently as a way to screen babies.
James Woods, a researcher at the University of Washington who worked on the project with Battelle researchers, noted that everybody has the compounds in their urine, but the levels were clearly higher in certain children in the study. Also, although the study included only boys (who are much more likely to have autism than girls), Woods said that the test would likely work for both genders based on other research.
Heyer noted that although there’s been speculation that elevated porphyrin levels are related to mercury exposure in autistic children, the research team found no link to increased exposure to mercury. This leaves the question open of why the compounds are higher in some children with autism.
