AlterMe uses a cheek swab method to collect DNA samples for its genetic testing services. This method involves gently swabbing the inside of your cheek to gather cells, which are then analyzed for DNA. AlterMe does not offer blood tests as part of its services, focusing exclusively on the cheek swab method for DNA collection. The cheek swab method is non-invasive, easy to use, and effective for collecting sufficient DNA for analysis. It is designed to work for most individuals, including those with specific concerns such as chronic dry mouth, as the process collects cells from the cheek lining rather than relying on saliva.
