Hospital Paternity Testing Process Paternity testing refers to a method that uses DNA analysis technology to determine the parent-child relationship by comparing the genetic information between parents and children. Performing a paternity test in a hospital generally requires the following processes: consultation, sample collection, testing, and reporting. First of all, you need to consult the hospital for relevant information about paternity testing, including the nature of the test, sample collection, testing cycle, cost, etc. Subsequently, hospital staff will arrange for both parents and children to go to the hospital for sample collection.
