Blood relation can be proven by a DNA test, or by a chain of documents showing relation (ie grandmother's identification, then her child's information, and the grandchild's relation to that person - so via copies of birth certificates).
However, one need not be a blood relative in order to be appointed as conservator. If the individual is of sound mind, they can execute a power of attorney that authorizes the person appointed to act on her behalf as to all legal and financial concerns.
