If I buy multiple DNA collection kits from different companies, are my results going to be different?


I mean, is it like a blood test that tells you ar different points in time different things about your health?


No. So if I understand correctly, you want to send different samples to different companies. Your DNA stays the same, so the actual reading of the DNA is the same. What differs is if you want to perform different tests, like ancestry or fitness, then you might get slightly different results from different companies, depending on what algorithms they use.
