Is a Dna enough evidence for a 60 year old LPR mom petitioning for her son or are additional evidences required?

For purposes of an I-130 petition establishing relationship, a reliable positive DNA test will be accepted if done under USCIS auspices. The 60-year-old mother should include a letter in her initial filing as to the reason why she cannot supply the birth certificate of the child and wishes to rely upon DNA evidence.
