We were not told to undress and that's probably based on the answers to the previous questions like, Have you had a surgery before? Have you deliberately injured or did you have any thought of injuring yourself? (Guess that's trying to check for depression symptoms). what the doctor just checked was our stomach regions for adult. Told us to stretch our hands to our toes asking for any pain felt, lie down on your back, raise your legs to an angle to check for pain, checks your eyes, mouth,ear, try to pull your hand and tells you to restraint you. Am sure all these are to test for different things. Dr Bikerboy can help us out if he hasn't zoomed far away. Although it appeared really simple. For the kids less than 5, not much test was done, no urine, blood test or X-ray just physical examination. Also, weight,height,reading test with or without glasses, bp.
In all it was a simple process and I must say I quite admire their professionalism at Q-life. Best wishes bro!
