Right, but the data you get from that test is pretty broad. One test will create a background for an entire family. You only need to do one for one child. Or if both parents have one, or a sibling of both parents have done one, the children of that pair also no longer needs a test to see their background.
It’s not just about background though. Could also filter the results for genetic markers of medical conditions, something that may differ between individuals.
