This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
This study is trying to understand how people with autism spectrum disorder experience blood tests differently than others. Researchers will video-record your face and body movements, measure your heart rate using a wireless watch, and ask you questions about your emotions and pain during a routine blood draw that you're already scheduled to have for medical care.
Blood tests can be stressful and painful for anyone, but people with autism may experience and express anxiety or discomfort in different ways. This research aims to better understand those differences so doctors can provide better support and care during medical procedures.

You will wear a small wireless watch on your wrist that tracks your heart rate during your blood test. While the blood draw happens, a camera will record your facial expressions and body movements in a standardized way. Before and after the test, you (and a parent or caregiver, if applicable) will answer brief questionnaires about what emotions you felt and how much pain or anxiety you experienced. The whole process takes place during a routine blood test you're already scheduled to have.
