The company I use in my office, I've used for I don't know over 10 years, is Marriott. And um the reason I use this specific company, there are a lot of companies that check for genetic cancer testing, right? They check 80 90 genes. I think Marriott only checks 63 genes which is fine. But so not only Marriott checks you for the cancer-causing genes, they also calculate your tire cus for you so the doctor can see it. But in addition to that, Marriott takes your tire and also looks in the DNA for tiny little markers.
