[The Thing] Could the Thing replicate tattoos?

In the 1982 version, a blood test was done to confirm who has been assimilated.  In the 2011 prequel, the survivors check each other’s teeth for fillings, because the Thing cannot replicate inorganic objects.

By this logic, it wouldn’t be able to replicate tattoos, right?  And would giving tattoos be a valid method to identifying who’s human?

Not sure it would distinguish between tattoos and birthmarks. It might not replicate the synthetic ink but it could accomplish the same thing with the same natural pigments that it used to color the rest of the body.

(and the, you know, clothes)
