Once you've received your DNA test results in some kind of computer file, the next step to make it useful here at WikiTree is to register at another website called GEDmatch.com and follow GEDmatch's directions for uploading your DNA data file there.
Here's a WikiTree help page to answer your questions on how to take it from there:
WikiTree Help: GEDmatch
https://www.wikitree.com/wiki/Help:GEDMatch
GEDmatch is a free website that takes information from a variety of different autosomal DNA testing websites (such as AncestryDNA, 23andMe, MyHeritageDNA or FamilyTreeDNA) and organizes it in a database from which you can more readily compare DNA results with others who've also shared their DNA test results at GEDmatch. GEDmatch also offers highly-advanced tools that you can't find anywhere else.
When you enter a GEDmatch ID on a DNA test on WikiTree, GEDmatch will automatically link to your compact family tree on WikiTree when you appear in one-to-many results--and you can take your GEDmatch ID and include it here at WikiTree.
