A new test claims to assess a child’s risk of autism based on abnormal folds in the placenta, and is being offered to pediatricians in the U.S. But with little evidence to support its use, experts say the test is premature and unethical.
Already, he says, parents ship thousands of freshly delivered placentas to his lab each year, though he declines to say how many are analyzed for autism risk. Some reports indicate the test could cost upward of $2,000.
Autism experts are not impressed.
“I am truly appalled at the rush to market a test that has such weak predictive power to vulnerable families,” says Helen Tager-Flusberg, director of the Center for Autism Research Excellence at Boston University.
Researchers note that no other peer-reviewed reports have linked placental folds to childhood disorders, and none establish a firm link to autism. Kliman has also not yet confirmed autism diagnoses for children whose placentas he examined at birth.
These unknowns call the test’s predictive power — and ethics — into question, says Catherine Lord, director of the Center for Autism and the Developing Brain at New York-Presbyterian Hospital. “The idea that this is being marketed without fully acknowledging its limitations is scary,” she says.
