Two men are suing a hospital in North Dakota after DNA testing led them to conclude they were switched at birth about 38 years ago, according to reports. The lawsuit is brought by families of the two men who say the discovery came through DNA tests and that the men were raised believing they were the biological children of different parents. The plaintiffs accuse the hospital of causing harm by allowing the birth switch to occur and by depriving them of the lives they would have had if they had been raised with their biological families.

ABC News reports that the families argue the hospital’s actions—or failures—resulted in lasting consequences for the men. The Independent and Winnipeg Free Press also describe the case in similar terms, focusing on the alleged birth switch and the use of DNA testing to uncover it. The reporting does not indicate, at this stage, who the hospital says is responsible, whether the hospital disputes the findings, or whether the switch is definitively attributed to a specific staff error. The case remains a legal matter as it proceeds through the court system.
