Basically, yes. But test is costly, and won’t be of any help other than telling me “You’re a Chimera, Harry”.
Sure, Chimeras are more likely to get some diseases , like autoimmune one (because the immune system suddenly realizing your left kidney isn’t exactly yours 😅), and depression (dunno why 😅).

So for now I’ll just deal with my naturally multicolored body hair (dark brown, some very blond patches, and some ginger bits), and move on.
Now that I think about it… I’m a human calico 😆
