As a middle ground between DIY and leaving it unknown you could also hire a contract lab to do this with you. As an experiment in this, I found a contract lab, ordered PCR primers, and sent in McDonalds burgers and McFish samples to do species identification. (Result: $300 all in, nothing too exciting, Bovine and iirc Alaskan Cod). The "human sample" bit might be tricky. Doing this today I would check out https://www.scienceexchange.com/ https://www.scienceexchange.com/ Oh and obviously if you're in the Bay Area go to BioCurious (https://biocurious.org/ https://biocurious.org/) or Counter Culture Labs (https://www.counterculturelabs.org/ https://www.counterculturelabs.org/) for all your DIY bio dreams
