"My adult child stigmatised for mental health illness"

My adult child has a mental health illness and needs to have regular blood tests to check for therapeutic levels of their medication. Yesterday, my child presented at the Reception Desk and was asked to take a seat. The environment was calm, my child was very relaxed and I told the nurse that I had faxed the pathology request the day before.

Then another nurse walked past and nodded me on my shoulder saying that from now on, I had to accompany my child while their bloods were taken and that staff were going to call security to come over to assist. My child became angry that security was called and asked the staff member at the desk what they had done wrong to justify the request for security attendance. My child did not receive a satisfactory answer and was told to sit and wait. My child had their blood test without conflict. I feel the whole process was unnecessarily very stressful for my child and myself. We will be attending a different pathology centre from now onwards.
