Modification of Custody: How Can a Parent Avoid a Court-Ordered Drug Test

My question involves a child custody case from the State of:Ohio.... We just got out of the courts. My Friend has raised her child as a single mother. She's worked 100 hr weeks, Graduated college with a business degree, and through all, always supported her child having a relation with father and his family. She was practically best friends with his mother. She left him because he was stuck on hard drugs. Their boy is now 3 years old. His father ordered an immediate exporte about 2 months ago behind my friends back. In Court today she represented herself. She did all compliance of Court leading to today. She was ordered to take urine and Hair follicle test in which defendant, the father had to pay. ( When she reported, as soon as she received from sheriff, the father refused to pay so the testers made her log in and recorded time. ) The Judge asked them to do mediation, My Friend (women) agreed and even told the counseler she'd pay for the fees, The Defendant refused. The Defendants Family and Friends all Lied to courts. They said the father has always been the good parent, Never had drug issues and flipped the script on to her. They have money and she doesn't. They have kept her son from her for the last 2 months, I've heard him call her (n... lover word) because at one point she had dated an African American, state u will never see you child again, belittle her, for last 2 months. She has drank alittle more and the problem is that she has smoked trees I know. I think she did awesome representing herself today. but at the end the courts continued case and ordered test to be done again within 24 hr. Does She have the Right to refuse test after? Can She Postpone or delay Test? If refuses or misses test what will the pentalty of being held in contempt be? Can she just skip test tomorrow and just state she won't take test and ask to go to trial because I believe she did a great job in proving her case as a good mother and called them out on so many lines? Please help with suggestions as fast as please. I have watched her suffer and I believe if she does these tests it will be the only hard evidence to prove fathers case. She's a fair, Just , Mother that has always supported her son's well being. We have a friend that says he can help even get attorney if we have too at this point. ..please help with any suggestions. Thanks and God Bless
