Section 1038-A. Discovery; upon court order

Upon motion of a petitioner or
  law guardian, the court may order a respondent to provide nontestimonial
  evidence, only if the court finds probable cause that  the  evidence  is
  reasonably  related  to establishing the allegations in a petition filed
  pursuant to this article. Such order may include, but not be limited to,
  provision for the taking of samples  of  blood,  urine,  hair  or  other
  materials  from  the  respondent's  body  in  a  manner not involving an
  unreasonable intrusion  or  risk  of  serious  physical  injury  to  the
  respondent.
